Re: [R] Can data.frame be saved as image?
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.

Subject: [R] Can data.frame be saved as image?
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

Re: [R] Can data.frame be saved as image?
Dear Sir,
Thanks a lot for your suggestion. In the meantime I came across
http://stackoverflow.com/questions/10587621/how-to-print-to-paper-a-nicely-formatted-data-frame
and got to know about the package "gridExtra"
So I used following code
png(filename = "output1.png", width=480,height=480)
grid.table(output1)
dev.off()
And that solved it.
Thanks again Sir for suggesting other two pacakages 'lattice' or 'ggplot2' as
definitely I will like to decipher these two.
I understand before posting the mail to the forum, I should have tried old
mails etc, but I was bit desperate to know the solution and somehow I felt it's
a stupid thing to do so. I will remember it next time.
Regards
Katherine

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?

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