[R] boxplot with frequencies(counts)
Dear All, I have a table as following position type count 1 2 100 1 3 51 1 5 64 1 8 81 1 6 32 2 2 41 2 3 85 and so on Normally if would have a vector of 2,3,4,5... by position position and plot them by position. But now i have counts of these types. Is there a way to compute boxplot of such kind of data ?

[R] long vectors in R 3.0.x
Dear All,
I understand that we could use long vectors like this beyond 2^31-1 limit.
x<- c('0')
length(x)<- 2^35
But how do I do introduce this notion in matrices ? specifically if i want
rows > 2^31-1 limit ?
Regards,
Krishna Mohan

Re: [R] book about "support vector machines"
a bit of caution.
the latest version of libsvm is not yet available in the e1071 R-package.

[R] saving plots
Hi all,
Is there a way to save the currently displayed plot to an image format just
after we view it?
I think this would be more intuitive as a user if I wish to save it just
after I visualize the plot.
I am aware that we need to do some thing like this
jpeg('somefilename.jpg')
... plot... commands...
dev.off()
