Hi Christophe,
No, there isn't anything close to savePlot() on either Linux or MacOS.
But the difference is that savePlot() is used to save something that has
already been plotted. Since your function appears to be intended to give
the user the ability to save something that has yet to be plotted, you
could simply use a switch() statement in the body of your function:
switch(type, pdf = {
pdf("plotname.pdf")
plot(<something>)
dev.off()
},
jpeg = {
jpeg("plotname.jpg")
plot(<something>)
dev.off()
},
png = {
png("plotname.png")
plot(<something>)
dev.off()
})
You can also plot things first and use recordPlot() and replayPlot() to
emulate savePlot(). In addition, you can get tricky and check to see if
the version of R being used is capable of doing a particular plot type
using capabilities() and then trapping errors where the end user wants
to create a plot that their R installation won't do.
Best,
Jim

Hi all,
In the package rtlu, I use the function savePlot. It is convenient since
it let the user decide in which graphic format he wants his graph to be
export.
But when I run R CMD check, I get the following message :
rtlu(V1,fileOutput="First.tex",textBefore="\\section{Variable 1 to
3}",graphName="V1")
Error in savePlot(filename = nomBarplot, type = type) : can only copy
from 'windows' devices
Calls: rtlu ... r2lUniv -> r2lUniv.factor -> r2lBarplot -> savePlot
Execution halted
I guess this is a compatibility problem with Linux/Mac? Is there
something close to savePlot for Mac / Linux?
Christophe
