[R] X11 PNG Error

Hi All, I am running R 2.6.0 on an Ubuntu 8.04 with Rserve on a machine. I send R commands from a Windows computer to the R machine and a few commands require the creation of plots on png devices. I often get the following error: Error in X11(paste(png::, filename, sep = ), width, height,

Re: [R] X11 PNG Error

1) Please follow the posting guide: a later version of R will solve this. 2) Please read ?png in the version you have: it describes how you need write access on a running X server, and how to use Xvfb to get this if neccessary. On Mon, 29 Dec 2008, Harsh wrote: Hi All, I am running R 2.6.0

I monitored the usage of memory on a script that I ran. It ran 30K regressions and it stores p-values for one of the coefficients. It read in a file that has 3000 rows and about 30K columns. The size of the file is about 170 MB. My understanding is that memory usage started out at 2.2G and went
