Esteemed R Users,
Would some one be patient enough to explain the variation i see when
creating .pdf file output for my plots? FYI- my goal is produce the
highest quality .pdf output from the R 'command line' as opposed to
using the menu of the acitve graphics window.
Im using 32bit WinXP. Session info at the bottom. I have Ghostscript
v8.71 installed and in the Path such that C:\gswin32c.exe runs said
program.
All shared insights appreciated!
Karl
Method 1:
In the R graphics device window, form the menu File>Save As>PDF
-yields a .pdf file of 700Kb (in this plot example)
Method 2:
> dev2bitmap(file="expression.density.plotb.pdf", type = "pdfwrite",
> method = "pdf")
> dev.off()
-yields a .pdf file of 300kb (same plot example) indistinguiashble (on
the screen atleast) from method 1.
Method 3:
> pdf(file="my_plot.pdf", paper="a4")
> dev.off()
-yields a .pdf file of 1kb (same plot example) and returns the following
error when attempting to open with Adobe acrobat:
"There was an error opening this document. This file cannot be opened
because it has no pages."
