In R, whith:
pdf(file="path_to_file/filename")
makeVennDiagram(ol)
dev.off()
or:
png(file="path_to_file/filename")
makeVennDiagram(ol)
dev.off()
I get the error:
Error in dev.off() :
QuartzBitmap_Output - unable to open file 'path_to_file/filename'
and doesn't save the graph in the folder. Does someone know what is causing this error?
## Do this in a fresh R session
# First get the working directory of R. Your plots will be saved here
getwd()
# Then give the pdf output file a name
pdf(file="myFile.pdf")
makeVennDiagram(ol)
dev.off()
If everything goes fine, you should get the plot in the file "myFile.pdf". Post the error if there is a problem again.
You have used "..." as filename. Any file starting with a "." are normally hidden to the end user; they will not be shown in GUI or by ls command unless you use 'ls -a'
"..." stands for path_to_file/filename, my mistake.
I tried as you said and it created a file in the working directory.
But shouldn't be possible to define the directory directly with png(file="path_to_file/filename") ?
that's correct, you could do that! Also you may change your actual directory to the place where you want to do all the calculations by using
setwd("path/to/dir/where/i/want/all/calculations")
it allows to setwd("path/to/dir/where/i/want/all/calculations") but with pdf("path/to/dir/where/i/want/all/calculations") it gives
error: Error in pdf(file = "path/to/dir/where/i/want/all/calculations") :
cannot open file 'path/to/dir/where/i/want/all/calculations'
as i can setwd(), the problem isn't with 'path/to/dir/where/i/want/all/calculations'
as i can setwd()
you can setwd() because this is a directory.
pdf("path/to/dir/where/i/want/all/calculations")
You can't create a pdf, because again, this is a directory. You need to give a filename (eg. myFile.pdf)
pdf("path/to/dir/where/i/want/all/calculations/myFile.pdf")
it worked out, thank you
