Can data.frame be saved as image?

do you want to save the dataframe used in the plot and then the plot
itself?  If so consider using 'lattice' or 'ggplot2' which create an
object for "print" and this would allow you to use 'save' to save both
objects in a file.

If you want to generate the 'png' file, the you would have to 'save'
the dataframe and then 'zip' the .RData and png file into a new file.

So what is it that you intend to do with the data that is saved in the
common file?

Dear R forum

I have one stupid question, but I have no other solution to it in sight?

Suppose some R process creates graphs etc alongwith main output as data.frame e.g

output1 = data.frame(bands = c("A", "B", "C"), results = c(74, 108,  65))

I normally save this output as some csv file.

But I need to save this output as some image (I understand this is weird, but I need to find out some way to do so) e.g. for graph, I use 'png' as

png("histogram.png", width=480,height=480)

.....................

..................

dev.off()

Please advise.

Regards

Katherine

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.

Hi Katherine,

You could try this:
library(plotrix)
png("katherine.png")
?plot(0:3,0:3,xlab="",ylab="",type="n",axes=FALSE)
?addtable2plot(1,1,output1,cex=2)
?dev.off()


A.K.
