similar to: Barplot + plot same scale

Hi, All. I have a barplot I am making that has a 2 line label: names(GC) <- c("Read-Off", "Spatial\n Transformations", "Vis Changes", "Plans", "Abandon") and here, Spatial Transformations should be on 2 separate lines. However, when I break it as above (with the \n), the "Spatial" part is pushed up so that it overlaps the Tick mark

I'm trying to shade part of a density plot. The code I'm trying (using the Old Faithful data as an example) is something like this: # The Old Faithful geyser data data(faithful) d <- density(faithful$eruptions, bw = "sj") plot(d) polygon(d[d$x>4], col = "wheat") I expected that the part of the curve to the right of 4 on the x axis should be shaded, but nothing

Eric B's response provided just the kind of quick & simple solution I was hoping for (appears as the function com below). However, I once again failed to take advantage of the power of R and have reverted back to using a for loop for the next step of the processing. The example below (which requires the library EGRET for pulling an example dataset) works, but probably can be replaced

Hallo, I'm dynamically generating buttons depending on the number of rows of my dataframe. Every button is supposed to call a function which generates a plot with the values of one of my dataframe rows. My code looks like this: base <- tktoplevel() plotten <- function(mat, namen, titel) { midpts <- barplot(height=mat, names.arg = namen, main = titel, las=2)

Dear all, When I use parallel function in lattice package, I want to label the y-axis with customized numbers. Like this: parallel(~iris[1:4] | Species, iris,horiz=FALSE,common.scale=TRUE, scales=list(y=list(at=c(0,2,3)))) But only "Min" label in the y-axis, nothing happened. Could anyone help me? Thanks. Regards, Pengcheng Yang

Hi Eric, the following works for me. HTH, Eric library(EGRET) StartDate <- "1990-10-01" EndDate <- "2017-09-30" siteNumber <- "10310000" QParameterCd <- "00060" Daily <- readNWISDaily(siteNumber, QParameterCd, StartDate, EndDate) # Define 'center of mass' function com <- function(x) { match(TRUE, cumsum(x/sum(x)) > 0.5) -

Hi Eric, How about match( TRUE, cumsum(hyd/sum(hyd)) > .5 ) - 1 HTH, Eric On Sat, Dec 16, 2017 at 3:18 PM, Morway, Eric <emorway at usgs.gov> wrote: > The small bit of script below is an example of what I'm attempting to do - > find the day on which the 'center of mass' occurs.

Dear all I apologize for cross-posting, but first it is accepted custom to thank the repliers and give a summary, and second I have still the feeling that this problem might be a general statistical problem and not necessarily related to microarrays only, but I might be wrong. First, I want to thank Robert Gentleman, Mark Kimpel and Mark Reiners for their kind replies. Robert Gentleman kindly

The small bit of script below is an example of what I'm attempting to do - find the day on which the 'center of mass' occurs. In case that is the wrong term, I'd like to know the day that essentially cuts the area under the curve in to two equal parts: set.seed(4004) Date <- seq(as.Date('2000-09-01'), as.Date('2000-09-30'), by='day') hyd <-

This is not related to R but I was hoping that someone could help me. I am reading the "Understanding the Metropolis Hastings Algorithm" paper from the American Statistician by Chip and Greenberg, 1995, Vol 49, No 4. Right at the beginning they explain the algorithm for basic acceptance rejection sampling in which you want to simulate a density from f(x) but it's not easy and you

Hello everyone, i am currently creating a barplot. This barplot takes a vector of ~200 datapoints. Each datapoint represents one bar. http://img96.imageshack.us/i/human1w.png/ (Ok as you see, it is not only one barplot, but a series of barplots). Now, these barplots represent a human chromosome. This means they are ordered. For instance bar number 50, means position 50 in the human chromosome.

Hello. Does anyone know how to get barplot to plot in log scale? I tried: barplot(Mx, log="y", besides=F), where Mx is a 2 by 31 matrix to be plotted. R complains: Error in plot.window(xlim, ylim, log = "", ...) : formal argument "log" matched by multiple actual arguments I know there's nothing wrong with the rest of the arguments because if I took

Hi, I have a large amount of data that I would like to create a histogram of and plot and do things with in R. It is pretty much impossible to read the data into R, so I have written a program to bin the data and now have a list of counts in each bin. Is it possible to somehow import this into R and use hist(), so I can, for instance, plot the probability density? I have looked at the help page

Hi, I have data that is on a log base 2 scale. It goes from negative factors of 2 to positive ones. I am using barplot. However, I don't want the data centered at 0 - I want the min of the yaxis to be just below the lowest value in the data. The plots are kind of deceptive switching between positive and negative. I see that barplot has a log option, but that doesn't seem to be

As part of my work, I am trying to append matrices onto data frames. Naively I assumed that when rbinding a data.frame and matrix, the matrix would be coerced and appended, keeping the names from the data frame. Clearly, I am not fully understanding the process by which rbind works. Example code: > A<-data.frame(1,1,1); names(A)=letters[1:3] ; B<-matrix(0,2,3) > rbind(A,B)

Dear all, might there be a modified barplot function out there which allows the user to specify a fill color for the bars and independent parameters for the overlaid shading lines ? Currently, when I specify density and col, the fill color for the bars is white. Thanks! Markus [[alternative HTML version deleted]]

Hello R-Experts, I am a beginner to R. Can someone please look at my problem I am trying to append the files in R but couldn't get the answer properly. My code is mat1<-matrix(0,2,3) mat2<-matrix(1,2,3) write.table(mat1,"foo.csv",sep=",",col.names=NA) write.table(mat2,"foo.csv", sep=",", col.names=NA, append = TRUE) I am getting a warning

Greeting R Community, I'm trying to learn Logistic Regression on my own and am using An Introduction to Logistic Regression Analysis and Reporting (Peng, C., Lee, K., & Ingersoll, G. ,2002). This article uses a Score Test Stat as a measure of overall fit for a logistic regression model. The author calculates this statistic using SAS. I am looking for an [R] function that can compute

Hello everyine, I am trying to run R in Batch mode in windows, but can't find any help in google. In particular, the only information I get is that I need to have an R.exe file, than I can't find in the bin folder. Can you please provide me with a link or refence on how to run R in batch mode in windows. I can do this very easely in unix, but not in windows.

Dear Samba Users, I am preparing a Samba box as standalone server (only files server, centos 7). This Samba box is a domain member server, and is dedicaded to serve files to about 80 domain users. I am wondering if there are some special requirements for this purpose in terms of CPUs, Memory ? The Samba box is a Vmware virtual machine, so I can easely configure this. I noticed also in some
