png package in Ubuntu 12.04 with R 3.1.0

Dear All,


I am using R to analyse computer simulations of ligand docking in a protein.

I am plotting the results as scatterplots and bopxplots, using the code below.

This works perfectly fine.


I would like now to add a png file to that plot, meaning I want sth like:


png(file="analysis.png")
par(mfrow=c(1,3), oma=c(0,0,2,0))

plot

boxplot

PNG figure I read in


I am running Ubuntu 12.04 and R 3.1.0.


readPNG and the png packge do NOT work for me at this point.


when I try to install the png package I get the error below.


Any ideas what's wrong or other options to import png files?


Thank you in advance for the help.


Best regards


Gudrun



png(file="analysis.png")
par(mfrow=c(1,2), oma=c(0,0,2,0))
plot(data, main="all", xlab="simulations run", ylab="steps")
boxplot(data, main="steps", horizontal = FALSE, axes = FALSE, staplewex = 1)
text(y = boxplot.stats(data)$stats, labels = boxplot.stats(data)$stats, x = 1.35)
title("analysis", outer=TRUE)
