To read in a few columns you can can also use something like,
reduced.data<-do.call("cbind",scan(file='location/name',what=list(NULL,NULL,NULL,NULL,NULL,NULL,NULL,0,NULL,0,NULL,NULL,NULL),flush=TRUE))
where only columns 8 and 10 where saved in your object.

Jason -
colSums does return an object of class "numeric", which is certainly a
vector. The vector it returns happens to have names. If you want an
unnamed vector of the sums, just set the names attribute to NULL. This
will remove the names. However, you say you can't figure out how to

I would like to use GNUplot for the plots, but I can't find any
information on how to do that.
Have anyone tried that? =)
Hugs,

Dear list,
I'm trying to write my first looping function in R. After many hours of
searching help files and previous posts, I'm at wits end. Please forgive my
programming ignorance...any help is greatly appreciated.
I need to sort through a vector (x) and identify the point at which 2

Does this give the answer that you want?

Hello,
I'm using the R package called mvpart, which is about the multivariate
regression trees.
The function I wrote is:
mrt1<- mvpart(coefmat~sChip+sScreen+sMem,data=mixdata, xv="pick",
plot.add=TRUE,uniform=TRUE,which=4,all=TRUE,xadj=2,yadj=2,rsq=TRUE,big.pts=TRUE,wgt.ave.pca=TRUE,legend=TRUE,ba
Still about the mvpart.
Is there any way I can control for the number of elements in each node
in the function mvpart? Specifically, how can I ask partition to
ignore node with elements less than 10?
Thanks!

Dear Prof. Ripley,
Thanks for your reply. I think I understand now.

Okay, my post was not very good.
The reason (I think) I need GNUplot, is tha

mvpart is just a wrapper to (a modifie
I believe that R can export all formats that GNUplot can produce,
so i don't really see why you want to use GNUplot if you don't know it.
If you still want to then read ?write.table, that can export your data
into a spreadsheet-like ascii format which can be used from GNUplot
easily.
Btw, compar

But there is no native Mac program to open a dvi file.

PLEASE do read the posting guide

minimal, self-contained, reproducible code.
Here is an example; I am not sure what problem you are having with
'indexing' since you did not show an example.
> x <- data.frame(a=1:10, b=21:30, c=41:
I have the following code:
subsetTimeDataPlot <- boxplot(subsetTimeData$time ~
subsetTimeData$build, horizontal=True, col="lightblue", ...)
The 'names' component consists of strings that can be up to 20-30
characters long.
How would I go about drawing the names vertically (not the boxplot) or
1 - 100 of 117 matches
