Hello. I have made many pngs in the past, but started having trouble with
them yesterday. I just downloaded R 2.13.0 this morning, and was able to
make some pngs earlier this morning. Now I am trying to remake them, but
get the same error message I got yesterday:
> u='in'
> w=10.5
> h=8
> png('winbugs changepoint graphs ind hibs gt 400
p%02d.png',height=h,width=w,res=300,units=u)
Error in png("winbugs changepoint graphs ind hibs gt 400 p%02d.png", height
= h, :
unable to start png() device
In addition: Warning messages:
1: In png("winbugs changepoint graphs ind hibs gt 400 p%02d.png", height =
h, :
Unable to allocate bitmap
2: In png("winbugs changepoint graphs ind hibs gt 400 p%02d.png", height =
h, :
opening device failed
This exact same script worked an hour ago! I have tried closing R and
re-opening it, but I am getting this error message every time now. I cannot
make any sense of this, and the posts that I have found have not helped.
One said that I could use bitmap(), but then I would need to install
ghostscript, and I don't have priviliges to do so. If anybody knows how I
can fix this, I would really appreciate some guidance.
