Hi All, I have a rather naive question. I need to run some simple calculations such as read.table, resid, and quantile on a data file. How can I save these commands in a text file and ask R to run this text file? Thanks.

Hi All, I had 12766 elements in a column, 12566 are values and 200 are "NA"s. I used the following line to get the ranks: total_list$MB.rank <- rank(-total_list$MB,ties.method="min",na.last=NA) but I got an error message: Error in `$<-.data.frame`(`*tmp*`, "BCRP_PW_F.rank", value = c(3949, 6182, : replacement has 12199 rows, data has 12766 What

Hi All, I typed "pairs" to see its code but did not get what I want. How do I see its code? What I am trying to do, is to stack about 10 scatter plots on one page as the way "pairs" does. I have about 150 variables in my table. Instead of plotting 150X150 pairs using "pairs", I only need to plot 10 pairs. Thanks. jiong The email message (and any attachments) is

I want to qqnorm every column in a table. When I try the first column using qqnorm(table$column1), it worked. But when I use qqnorm(table[1]), it tells me "Error in stripchart(x1, ...) : invalid plotting method". What happen? How can I make a function that qqnorms every column? thanks a lot. -jiong The email message (and any attachments) is for the sole use of the intended

Hi All, I want to give ranks to elements in a column so I used: total_list$field1.rank <- rank(total_list$field1,ties.method="min") But this gives me the rank in increasing order. How do I get the ranks in decreasing order? I know decreasing = FALSE is not a legal argument here. Thanks.

Hi Jiong, I don't have any special advice here. It sounds like the general functionality level is high enough. Taking it into mainline sounds great, so long as it is reviewed by someone. -Chris > > >

thank you, achim. I will try chol2inv. sandwich is a very nice package, but let me make some short suggestions. I am not a good econometrician, so I do not know what prewhitening is, and the vignette did not explain it. "?coeftest" did not work after I loaded the library. automatic bandwidth selection can be a good thing, but is not always. as to my own little function, I like the

Thanks, Eran. I’m not sure how soon I’ll have a solution for you, but it’s on my to-do list now. I’ll also create a bugzilla record for this problem. -Andy From: Weiss, Eran [mailto:Eran.Weiss at emc.com] Sent: Thursday, April 11, 2013 12:40 AM To: Kaylor, Andrew Cc: llvmdev at cs.uiuc.edu; Jim Grosbach; Jiong Wang Subject: Re: [LLVMdev] Migration from JIT to MCJIT Andrew, I've attached
