Re: [R] Can R handle a matrix with 8 billion entries?

too many entries for R’s architecture to know how to store in memory, even if I had memory that was big enough to store it. Again, I’m no expert in this so I may be wrong. Chris Howden Founding Partner Tricky Solutions Tricky Solutions 4 Tricky Problems Evidence Based Strategic Development

Re: [R] is there a way to update both packages if they occur in 2 libraries?

guessing the problem I was having would occur when ever this happens and people have the old package in their personal libraries. (which would likely be the case if it's considered good enough to add to base R) Not really a 'bug' of R. But something I'll remember!!! Thanks again. Chris Howden

Re: [R] is there a way to update both packages if they occur in 2 libraries?

Thanks for the explanation Brian, I used the summary(packageStatus()) to have a look at what was available and in each library. And then deleted all libraries that came with R2.12.0 from my personal library. And everything now works. Chris Howden Founding Partner Tricky Solutions Tricky

Re: [R] data from SpatialGridDataFrame

I'm not that familiar with this type of data. I just had a similar issue, but had a GIS person do it in Arc view. But maybe try some of the following functions? Match %in% Plus I'll forward U the replies I got to my post Good luck :-) -Original Message- From:

[R] do the standard R analysis functions handle spatial grid data?

data.frame or matrix? Are there other special functions out there that can handle this type of data, and I should be using these instead?
