[R] writing R output to a specific file type
Is it possible to write R-output to a specific file type? Specifically is it possible to write to a specific cell in an MS Excel spreadsheet?

Re: [R] Warnings about user error (was read.table error)
Prof. Pipley First let me thank you for your help. Second, you are correct, I should not have used the word error in my subject line. Regarding the lack of detach(), I simply forgot to include that in my email. The warnings regarding the incomplete final line do not seem to want to go away. The masking messages The following object(s) are masked from ovendata ( position 4 ) : D Eight Five Four One Seven Three Two do go away if I use: rm(list=ls(all=TRUE)) thanks, Eric - Original Message - From: Prof Brian Ripley [EMAIL PROTECTED] To: Eric C. Jennings [EMAIL PROTECTED] Cc: r-help@stat.math.ethz.ch Sent: Wednesday, December 07, 2005 11:05 PM Subject: Re: [R] Warnings about user error (was read.table error) I see no error here, let alone an error in read.table as claimed in your subject line. The posting guide does specifically ask `Use an informative subject line'. Please distinguish warnings about _your_ usage from errors in R. The first warning is that R fixed up an error in your file: it is missing a newline at the end of the last line (we can't see that in your listing). The remaining warnings come from attach() and say you have already repeatedly attach()ed ovendata. Learn to use detach() to match attach(). Also, in attaching ovendata you mask the function D in package stats, which is probably OK as you are not using it, and your D is a not a function. On Wed, 7 Dec 2005, Eric C.

[R] values in between

I understand subsetting with y[i], but how do I get to ssomewhere in between -0.6 and 0.2?
