Sorry I should have been more clearer. Let me repharse.
At the moment I have a loop that plots a histogram of the variable, along
with rug and super-imposed normal curve over it. It does that for a lot of
variables in the dataset and then compiles them into a pdf. Whereby each
page on the pdf corresponds to the histogram of 1 variable.
However, it takes ages to load and takes up a lot of memory. So I was
wondering if there is a way that before it gets compiled into a pdf, if I
can convert my graphs into png or bitmaps images and then compile them
into pdf?
This is my code so far:
pdf(file="C:/#temp/Histo and2.pdf") ##- Saves all plots in the same pdf
file
for(k in 1:ncol(nums2)){ hist(nums2[,k],freq=F,col="lightblue1",
#density=20 ##- Density -> Gives shaded bars
main=names(nums2)[k],col.main="blue",cex.main=0.8,font=2,
xlab=names(nums2)[k]) ##- Font=2 => bold
#rug(jitter(nums2[,k]),side=1,col="antiquewhite3")
lines(density(nums2[,k],na.rm=T),col="navy",lwd=2) ##- Density
Function of data
curve(dnorm(x,mean=mean(nums2[,k],na.rm=T),sd=sd(nums2[,k],na.rm=T)),
col="brown",lwd=3,add=T)
# readline(prompt="Press [enter] to
continue")
}
dev.off()
Hope this is much clearer?

Sounds like you are getting what you want... except that you used the word
"but". If you are not getting what you want, then what is it that you do
want? In particular, how do you intend to review or use many plots
generated at once if not in a PDF file?
