How do I tell summary to not wrap columns?

Question

I am trying to get summary to not wrap its output. However, when I call summary with 5 columns of data, it places the 5th column on a separate row. I am hoping there is a way that's easier than manually printing iterating over the object returned by summary.

Best Regards,

Joseph

plotit.r

#!/usr/bin/Rscript
noneData <- read.csv("query.log", header=FALSE, sep="\t");
cnames = c( 'vids', 'partitions', 'localvert', 'remotevert',
                    'cachehits', 'responsetime' );
colnames(noneData) <- cnames;
cachenames = c('1', '2', '3', '4', '5');
responseCompare = data.frame(
   noneData$responsetime/1000000,
   noneData$responsetime/1000000,
   noneData$responsetime/1000000,
   noneData$responsetime/1000000,
   noneData$responsetime/1000000
   );
colnames(responseCompare) <- cachenames;
print("Response Times");
summary(responseCompare);

./plotit.r #output:

The options() function gives you a method of creating side-effects in the R console environment:

 names( options() )
 options(width=120) ; cat("Response Times"); summary(responseCompare)

The print method will then only add "\n" when it reaches a "virtual end of page" at 120 total characters. It calculates the width of columns and only prints a batch of columns at a time.
