Hello, I am facing a problem in drawing heat map using R. I have a 70X3 matrix and I want to draw a heat map with 1 coloumn on X axis another on Y axis and want to show the value of 3rd coloumn using heat colours. Could you please help me with this . Thank you . Regards, Sumit [[alternative HTML version deleted]]

Hi all A slightly off topic post, but one that I think someone out there in the NUT community could probably help me with. Summer is coming, and my office at home is getting hot... helped in part by the APC 3KVA UPS I have sitting under my desk. It kicks out heat like a bar-heater, even when there is almost no load on it (idle load is one PC, one switch, one wireless AP, and thats it). It is very warm to the touch, and just gets worse when I turn on the rest of the kit (tape autoloader, TFTs, CRTs, two other PCs). With the UPS kicking out heat, and the...

Hello, I have a large data set from RNA sequencing and I am trying to make a heat map of my data. I have am having issues formatting my heat map figure. My data set is large with the log2 fold change for over 6oo genes across 4 treatments. My csv file is formatted as such: Gene Drought Ozone Temp1 Temp2 Gly...

Hi, I have spatial data for plants that I would like to plot according to its radius using sysmbols(). Also I would like to color the circles according to an individual's age using heat.colors(17) [ages within the whole data set range from 0:16]. I have not found an easy way to assign ages (=a) a specific heat.color. Any suggestions? Thanks, Patrick x <- c(1,3,4,6,7,3,2,8,3,6,5,5) y <- c(0,5,4,2,7,6,4,5,3,7,9,2) r <- c(0.1,0.4,0.3,0.2,0.5,0.3,0.2,0.4,0.3,0.2,0.1,0.2)...

Hi all, I'm trying to using heat.color function in my data visualization. So, when I set col = heat.color(5), five different colors are displayed from red to weak yellow. But, now I want to know the color's keys or the names of the displayed heat.color. For instance, I think one of the five displayed colors seems to be 'r...

Hello All, I have a simple question based on how things are labeled on my heat map; particularly, there is this annoying "X" that appears before the numeric value of all the labels of my columns. Let's say I have the following silly data, stored in "temp.txt" 1905 1910 1950 1992 2011 2020 Gnat 0.08 0.29 0.29 0.37...

If I want to create a heat map where I have a graphic of a US State with county borders, how do I import and work with the graphic image? The reason I would like to use R is so I can then define color parameters and quickly produce heat maps that correspond to various data in dataframes.   Thanks. Alison [[alternative HTML...

Dear All, I would like to do the following: make a plot of the world and color a few selected states. Some states have an associated scalar (i.e a simple number) and I would like to paint them using a heat map and show legend for the color map in the plot. One or two states do not have any number associated to them and are simply colored/filled according to a distinctive pattern that I choose. To fix the ideas, imagine the following situation in which (1) the US are striped (or filled with any patt...

Hello, I've searched for help a lot and think I am close, but an still not able to place ticks and labels how I'd like in lattice's levelplot. I've come up with general reproducible code that gives the same problem as I'm having with real data: heat <- array(1:24,c(3,8)) require (lattice) ##basically I want a graph like this. depth y axis doesn't have ticks and labels at each place, but i want a tick and label at each value. through time x has ticks and labels where there isn't data, i don't want that! even better would be if...

Hello, I am trying to make a heatmap in R and am having some trouble. I am very new to the world of R, but have been told that what I am trying to do should be possible. I want to make a heat map that looks like a gene expression heatmap (see http://en.wikipedia.org/wiki/Heat_map). I have 43 samples and 900 genes (yes I know thi...

Dear R users, I have a question regarding how to make row labels readable in a heat map. I have successfully made a heat map using function "heatmap.2" in the package "gplots". However, as there are many rows in the heat map, I have difficulties labeling them (heatmap.2 provides a parameter "labRow" to label the row names, but as I have too many rows...

Hi all, I have read posts of heat map creation but I am one step prior -- Here is what I am trying to do and wonder if you have any tips? We are trying to map sequence reads from tumors to viral genomes. Example input file : 111 abc 111 sdf 111 xyz 1079 abc 1079 xyz 1079 xyz 5576 abc 5576 sdf 5576 sdf How...

Is there a simple way to put a legend outside the plot area for a simple plot? I found... (at http://www.harding.edu/fmccown/R/) # Expand right side of clipping rect to make room for the legend *par(xpd=T, mar=par()$mar+c(0,0,0,4))* # Graph autos (transposing the matrix) using heat colors, # put 10% of the space between each bar, and make labels # smaller with horizontal y-axis labels barplot(*t*(autos_data), main="Autos", ylab="Total", col=*heat.colors(3), space=0.1, cex.axis=0.8, las=1, names.arg=c("Mon","Tue","Wed",&q...

Hi friends, I have a problem i have VAIO VGN-F seies notebook which was performing slow on main power source, working fine on battery i did some tweaks on CPU speeds reading a lot of tutorials , i do not know whether this or somthing else has now started making mine notebook got heated up , i mean it is heatin up from base. I also have windows on the same system (dual boot), it was also heating up , i then installed NHC (Notebook Hardware Control ) on windows XP, it reduced the CPU speed and which probably increases load on the system, this removed the heating problem of CPU....

...R I have drawn indifference curves using the program below (Contour Plot) u <- function(x, y) x^0.5 + y^0.5 x <- seq(0, 1000, by=1) y <- seq(0, 1000, by=1) a <- c(10, 20, 30) contour(x, y, outer(x, y, u),levels=a,col="blue") Now can any body please tell me how to draw Heat maps and that too on the same indifference curve plot (contour) [[alternative HTML version deleted]]

Hi all! I want to generate a heat map from an all-vs-all comparison. I have the data, already scaled to 0-1. However, I have the values only for the comparisons in one way, and not for the comparisons between the same group (which are always 1), i.e. I have half the matrix and am missing the other half and the diagonal. What is...

I'm experiencing a very unusual problem with a few of my sipuras. They keep over heating after minimal usage. I unplug them and let them sit for 15 minutes and it starts working fine. The other way around is that I put a fan on it or something to keep it cooling. Has anyone else experienced this or are they just defective units? Regards, Mohammed Salim EZZI Telecom, Inc...

Dear List, Does there exist a function that produces a heat map like this one (image 3 of 4): http://www.tdameritrade.com/tradingtools/options360.html?a=HDY&referrer=http%3A%2F%2Fquery.nytimes.com%2Fsearch%2Fsitesearch%3Fquery%3Dheatmaptype%3Dnyt In addition to colors, two other main features I am intersted in are: 1. Proportionality in the size of t...

...a sealed cabinet >> filled with cooking oil. So they have a completely silent machine >> in 40C warm oil. Amazing... It certainly is. And, I suppose, this will work, for a while, as long as: The "sealed cabinet", has enough expansion capacity for the oil to expand from heating; Has enough surface area to effectively radiate the heat that is continuously generated, (else the temperature of the oil will continue to rise . . .(sound familiar?)) The components can withstand continuous (24x7x365) immersion in a heated liquid. A solvent, basically. The oil will eventuall...

Hi, I have a vectors x and z, for example, x <- 0:20 z <- round(runif(20,1,7)) y <- 0.5 and I want to display z as an image. However if I then call image() with a vector image(x,y,t(z),zlim=c(1,7),col=heat.colors(7),xlab="Year",ylab="Action",yaxt="n",xaxs="r",yaxs="r") then I get the error Error in image.default(x, y, t(z), zlim = c(1, 7), col = heat.colors(7), : dimensions of z are not length(x)(-1) times length(y)(-1) However, transforming z...
