similar to: custom tick labels on image

Hi, I'm having some problems with a bubble plot (ps package). I don't want tick marks on all four sides (just two), I want to have a smaller font size, and I would like to be able to define bubble sizes shown in the legend (now it shows 0, 0, 0, 9.747 and 4265.757 which is not really convenient. Passing some of the standard plot arguments didn't help (in fact, nothing changed).

Hi, I have a small set of data on which I have tried some normality tests. When I make a histogram of the data the distribution doesn't seem to be normal at all (rather lognormal), but still no matter what test I use (Shapiro, Anderson-Darling,...) it returns a very small p value (which as far as I know means that the distribution is normal). Am I doing something wrong here? Thanks Pieter

The data structures in R are still very puzzling to me. Can anyone tell me how I can easily convert these two dataframes to one single dataframe with two columns (mean and sd) with 7 rows? > meanprofile V1 V2 V3 V4 V5 V6 V7 2292.001 2178.620 1654.310 1784.004 1160.052 1142.061 1046.675 > sdprofile V1 V2 V3 V4 V5

Dear all, I am using filled.contour and my x-axis consists of a vector of dates, formatted using as.POSIXct. When I assign this vector to x in filled.contour, the x-axis in the plot is correctly formatted as dates. However, when I use plot.axes=axis(1) in filled.contour the x-axis is not correctly formatted. I need to opt for the latter because I want to add additional lines and points to the

Hello, I'm having problems reading a shapefile with read.shape (maptools). I'm absolutely sure my file is there, but I get "no such file". The wd is ok, since read.table for example does find the file. > getwd() [1] "D:/somedirectory/R scripts" > read.table("cities.shp") Error in read.table("cities.shp") : empty beginning of file In addition:

Hi, I'm trying to find a way to determine how many digits a number has. I tried using nchar(paste(number)), but unfortunately paste will reduce 8.00 to "8". Any thoughts?

Hello, I'm trying to find out how I can move the y axis label of a horizontal barplot further away from the axis, in order to avoid overlap between the names (which I have rotated using las=1) and the label. I have been fiddling with the graphical parameters but nothing seems to work. Maybe a graphical representation of the graphical parameters would be helpful (cf the CSS box model).

Quick question - I am having problems creating an orographic image (similar to volcano example). I have created a map matrix with 3 columns and over 2million rows. I have created the matrix as follows: map<-read.table("map.dat",header=TRUE) long.grid<-sort(unique(map$long) lat.grid<-sort(unique(map$lat) map.matrix<-matrix(map$height,nrow=length(lat.grid),byrow=TRUE) The

Hi, everybody! I am currently dealing with spatial estimation and thus writing some smoothing algorithms. My question concerns the graphical output. I would like my function to produce a picture of input data (X) and of estimation results(Y). Both, X and Y are categorical variables which can take values 1,2,...,Cl. So, basically I write foo<-function(){ ....

I searched the forms (i.e., R Search)?and come up with the following suggested link: ?http://cran.r-project.org/doc/FAQ/R-FAQ.html#How-can-I-create-rotated-axis-labels_003f I tried to implement what I believe was being implied by that URL and came up with the below: barplot(WorldPhones[1,], ??????? ylim=c(0, 50000), ??????? axes=FALSE, ann=FALSE, ???????

Dear All, I would wish to make multiple plots and give title/ headings same time, is there a simpler/ tidier way compared to below(, especially the headings as they are missing)?

Hello, I can't seem to add transparency to any color ramp I create using colorRampPalette(). Can someone tell me if it is possible to create transparent colour ramps? I am attempting to map shaded relief under elevation data. I know I can use the terrain.colors() with the alpha option, but I would prefer to create my own colour ramp using more vibrant colours. My most recent attempt at

In the following example I would like to have the color transition from Red->yellow->green in the image(...) function, and if possible have the yellow be set to correspond with the mean value (for the below 75). ? I was able to figure something like out when using filled.contour(...), e.g. filled.contour(ak.fan, levels = c(70, 73, 76,?80, 90), color = terrain.colors) (I still

Hi list, I wonder if anyone has had this experience with squishplot() in the TeachingDemos package. Taking the example from the ?image help page, library(TeachingDemos) x <- 10*(1:nrow(volcano)) y <- 10*(1:ncol(volcano)) layout(matrix(c(1,2,3,4),ncol=2,byrow=TRUE),height=c(2,1)) ## 1st plot op <- squishplot(range(x),range(y),1) image(x, y, volcano, col = terrain.colors(100)) par(op)

Dear list, I wish to visualise some 4D data as a kind of colour / translucent cloud in 3D. I haven't seen such plots in R (but perhaps I missed a feature of rgl). The easiest option I found would be to export the data in povray's df3 (density file) format and visualise it with povray. The format specification baffles me a little, http://www.povray.org/documentation/view/3.6.1/374/ ;

Hello R users... how to align this Zmat (triangle image) in X axis?
