r - Automatically save plot and associated code -

i save automatically each generated plot , associated code r session in specific directory.

i noticed rstudio stores every plots in temporary file (/tmp/rtmp*/*.png in linux). therefore .last function copies these files in save directory when close r. yet, copy associated code (i.e., ~ 10 last lines) these plots in *.rhistory files (using savehistory function). directory contain :

• plot1.png
• .plot1.rhistory
• plot2.png
• .plot2.rhistory
• ...

first thing me understand how rstudio plot function works did not find sources. assume uses dev.copy() dev.list() outputs :

plot(0) dev.list() > rstudiogd       png          2         3  

have ideas?

edit : looking @ rstudio sources, found in tools.r file savegraphicssnapshot function still not understand how works ...

first of all, rstudio front-end r, "understand how rstudio plot function works" is... understand how r plot function works. can google around find documentation.

now, point: simplest way output result of plot() file use functions listed here (by way, recommend take site... it's great learning resource r). in code, put relevant function:

# simple example: x <- rnorm(1000) pdf('mytestplot.pdf') # redirect output of plot() function                       # pdf file hist(x) dev.off() # "turn off" output "redirecting"... after invoking           # function, plots shown again in plot viewer 

other functions:

• png(): output png file
• jpeg(): output jpeg file
• and on

hope helps
