Hi Sir When I use install.packages("cvt') for installing packages using R 2.9.2 I have the following problem > install.packages("ctv") Warning in install.packages("ctv") : argument 'lib' is missing: using 'C:\Users\Amina\Documents/R/win-library/2.9' --- Please select a CRAN mirror for use in this session --- trying URL

This could be really trivial, but I cannot find the right function to get the name of an object as a character. Assume we have a function like: getName <- function(obj) Now if we call the function like: getName(blabla) and 'blabla' is not a defined object, I want getName to return "blabla". In other word, if paste("blabla") returns "blabla" I

Hello, I have the following question, which I haven't been able to resolve after days of trying. I used to save my plots as jpegs using the savePlot command. However, that seems to result in lost resolution. So now I'm trying to use the jpeg( ) function, but am having trouble because it seems to be incompatible with the windows (width=, height=) command. It's important for me to

Hi, I have tried to extract *.vhd* file using guestfs library. I am able to list all files inside my archive using *guestfs_ls* also * guestfs_list_filesystems()* retruns right File system information. I am trying to extract files from inside archive using *guestfs_copy_device_to_file() * but it returns following error (error: copy_device_to_file: unknown option 689330304 (this can happen if a

Dear Colleagues, Hope you will be fine. I am student of Ph.D and doing some work on distribution. I developed a new distribution and having some problems in estimating their parameters by MLE. I used R-program and  used "maxLik" function (maxLik: A Package for Maximum Likelihood Estimation in R) But there is some problem, it is not estimated the parameters properly. I also write an

Thanks a lot. I was trying to copy on local disk and guestfs_download () solved my problem. Now I am trying to modify source code of guestfs_download () to extract file in memory. Can you guide me what should i do to achieve that. Mohsin On Fri, Feb 10, 2017 at 2:13 AM, Richard W.M.

Dear colleagues, Saving a plot with pdf gives a very nice result: pdf("myplot.pdf") par(font=1,family='serif') plot(pressure) dev.off() Doing the very same with other formats (png, jpeg, tiff) gives far worse results. Is there anything to do to make a plot in some other format than pdf look like the pdf? Hardly any journal accepts pdf files for figures, and most do accept png

Hi, I've written a function in order to plot the same graph in a postcript and in a pdf file. Unfortunately, the second graph is always empty, i.e.: plot.both <- function{myplot, filename}{ pdf(file=paste(filename, ".pdf", sep="")) myplot dev.off() postscript(file=paste(filename, ".eps", sep="")) myplot dev.off() } yields in a

Dear all, I made a large plot and wanted to save it as a tif file. I first opened and specified the size of the window. windows(12,17,rescale="fixed") Then I plot a heatmap using heatmap() when I saved the plot by using "Save as" in the file menu or savePlot("heatmap", type="tif"), the plot in the output tif file is truncated. Only the upper part of the

Sorry for posting this twice, but I still have not solved this problem and am hoping for some assistance. I am attempting to write a function that is flexible enough to respond to the user providing a formula (with a data= argument) or not (similar to plot(x,y) versus plot(y~x,data=data)). I have found a method to work with this in a simple case but am having trouble determining how to

Hello all, I'm trying to write a function using the gridBase package. I'd like to push several base subplots to a larger plot constructed with grid. However, I'm having trouble getting consistent results when running the function when the plotting window (quartz) is closed, when it is left open and the plot function is repeated to the same window, and when the output is saved to a

Dear list, I've written a function that plots subjects. Something like: myplot <- function(subject) { plot(subject) } Subjects are vectors, e.g. ... s1 <- c(200,200,190,180) ... and plotting them works fine, e.g. ... myplot(s1) Now I want to have "s1" etc appear in the plot title, but I don't know how to refer to this generically (the object "name"? I tried

Dear R-helpers, I have a number of dataframes that looks something like this: mydfr <- data.frame(treatment=c(rep("A",3),rep("B",3)), Xmeas=1:6, Ymeas=c(2,4,3,3,5,6)) # except with many more variables, which I plot all the time colored by treatment to quickly check things: with(mydfr, plot(Xmeas, Ymeas, pch=19, col=c("blue","red")[treatment])) # I

Hello, Is it possible to call a graphing function that uses layout() multiple times and layout those outputs ? Here's a minimal example : myplot <- function() { layout(matrix(1:2, nrow=1), widths = c(1, 1)) plot(1:10) plot(10:1) } layout(matrix(1:2), heights = c(1, 2)) myplot() myplot() -------------------------------------- Dario Strbenac Research Assistant Cancer Epigenetics Garvan

Dear List, yes, me again trying to work with qplot ;-) I would like to make several single plots within a loop, like this (simplified and so on...): trials <- c("A","B","C") mycolours <- ("wheat","darkolivegreen","lightgreen",

Hi, I'm confused about the use of ellipsis in function arguments. I'm trying to write a wrapper for plot to automate the combination of plot() and points() calls for a data.frame. Some arguments seem to get passed through to the inner plot, while others cause an error: Error in eval(expr, envir, enclos) : ..1 used in an incorrect context, no ... to look in As a minimal example: tmp

Hi, I'm a new user trying to switch from SAS, so sorry for the beginner's question: Suppose I have a dataframe DF that contains variables X,Y,Z. I am trying to write a function like this: myplot <- function(varname){xyplot(varname ~ Y, group = Z, data = DF)}. The problem is then how to enter X into my function. If I write myplot("X") I get an error because the argument is a
