(Apologies the previous version was sent as rich text) Hello, I'm new to R, but I've read the intro to R and successfully connected it to an instance of mysql. I'm trying to perform multiple linear regression, but I'm having trouble using the lm function. To start, I have read in a simply y matrix of values(dependent variable) and x matrix of independent variables. It says both

...that sql statement saved as an Access Query in each db. Is this possible using R? I'm aware that I could use RODBC sqlQuery and write sql to make a table or that I could run the sql, extract it to R, and then use sqlSave to save the dataframe as a table in the db. thanks in advance, -- Tim Calkins 0406 753 997 [[alternative HTML version deleted]]

Hi everyone, suppose I have a 2D matrix, is there a command to snip out a specific row/column and then remerge the remaining columns/rows back into a contiguous matrix? I will need to repeat this operation quite a bit(reverse selection). Thanks for any insights you can offer. Yifei

Hi all. A question for knowledgeable folks using R on an Intel Mac running OS X 10.4.10 For ease of maintenance, I have broken a large R script into a main script which ?oversees? things by calling other scripts, using ?source?. Let?s call the secondary scripts ?sub-scripts.? I?d like for the sub-scripts to reside in a different directory (again, for ease of maintenance, and so I can access

Hi! Good work on Samba!!! for the %a: Are you going to recognize Win2K, WinXP, Win98?? This would help in keeping roaming profiles seperate for Win2K and WinXP - thanks! Patrick

Hi R-Experts, I'm having a problem with reading a large data file which is in .csv format and size is 120 MB (app.). I was trying to use RODBC package but I found RODBCconnectExcel function only. And can I convert this file to .dbf format? How can I read this file? And also let me know if this was a file in .sas7bdat format, what should I do? Thanks in advance.

Hi all, My apologies for a very simple question. I just downloaded R 2.6.0. I want to bring in all of the objects from 2.5.0 that I see when I type ls(). I have no idea how to do that.

Hi All Maybe I dont understand it, but I would have expected that the design matrix has as many rows as there were observations available to fit the model. Below a small artificial dataset created, then one model fitted and the design matrix outputted, having 27 rows. Then I delete 6 obs, and fit the model on these 21 obs, but the design matrix that comes out has 26 rows? Thanks for your

Hi all. i am desperating. i need a matrix of p.values from an chi square test. i had it already work but than my computer collapsed when taking the whole data set 800x260 into account. i am sure it looked like this but it doesn't work now. can anybody help me? thanks in advance. x=read.table("C:\...) d=ncols(x) z<=matrix(0,d,d) for(i in 1:d) for(j in 1:d)

Hi all, This question involves using a "for" loop to make a "decision" in a script. I've written a rather intricate script, and near the start of it, I want it either to do a loop (if a variable called "number.runs" > 1) or not do a loop (if "number.runs" is 1). This is probably trivial but I can't figure it out. Here's a self-contained

Hi, I am planning on putting some R script in an appendix of a LaTex document. Can anyone recommend me a way of how to format it? Is there a way to keep all line breaks without having to insert \\ in every single line? Thank you! Benjamin

Thanks, Tim To get the time difference in the proper units, it's as simple as this: difftime(myfileinfo$mtime[2], myfileinfo$mtime[1], units="hours") Cheers, Warren On 11/13/06, Tim Calkins <tcalkins@gmail.com> wrote: > hardly the most efficient way to go, but consider using a substring > function to extract the time bits from your data, then reading them as POSIX > dates and using difftime. > > for example, > > > mytime <- c("G2659310 2006-310-1...

Dear R-helpers, I am trying to generalize my function for recording measurement times from file times "mtime"--my intervals are minutes to hours over the course of several days. I want to use hours as my units, and I have had trouble dealing with time units in a general way. I have a simple solution for the dealing with regular intervals, but I have not been able to handle irregular
