Hi
I am generating a graph jpeg file using a function R. I m using this
script
a<- 1:10
b <- 1:10
jpeg("mygraph.jpeg")
{
plot(a,b)
}
dev.off()
If by some chance I do miss some values suppose for a , the file gets
created initially and then we do not plot anything in it.
This is not making sense, see below.
This file now
becomes corrupted and we cannot delete this file from current R
Session.
I Have tried commands like file.remove() and unlink to remove the
corrupt
file from current R session.
Is there any other way inorder to remove such files??
There was a question earlier this week that may have provoked an
answer that applies:
?graohics.off # followed by file.remove()
But I am puzzled. I would not have expected missing values in vectors
offered to a plot command to have resulted in a corrupted file and I
am unable to reproduce the behavior when I insert missing values into
the "a" vector. This suggests you may have more fundamental problems
with your installation of R (about which you have not provided the
requested information).
