Could anyone advise me how to allocate 1.5Gbyte memory for R on a Dell laptop running XP professional with 2G memory? I have tried "C:\Program Files\R\rw1081\bin\Rgui.exe" --max-vsize=1400M but I only get only 500MB for R actually.

Hi, What is the best text editor for programming in R? I am using JEdit as the text editor, however, it does not have anything specific for R.

Hi there, I am using DoveCot 1.0.7 and virtual users. We want to integrate with Postfix 2.3.3 to use DoveCot LDA to deliver messages to user mailbox. All users are stored in LDAP. DoveCot looks up user by LDAP access. Our user name is not necessarily part of the address. For instance, address "zhouy at xxxx" may be with user "yzhou", thus all messages to "zhouy at

Hi there, Is there someone over there knows a method or script that can copy a large volume of data (in folders) from PCs to a samba server (suppose there is enough space there)? I know using smbclient or smbtar can backup data on PCs to samba server, but it is written in tar files.I wonder whether this method can handle a large folder, say, in 10GB size. Also, using smbclient with mget and

I wrote a function to calculate cosine distances between rows of a matrix. It uses two loops and is slow. Any suggestions to speed this up? Thanks in advance. theta.dist <- function(x){ res <- matrix(NA, nrow(x), nrow(x)) for (i in 1:nrow(x)){ for(j in 1:nrow(x)){ if (i > j) res[i, j] <- res[j, i] else { v1 <- x[i,] v2 <- x[j,]

Hi there, I am using DoveCot 1.0.7. I know it is real old, but we have to work with it. I have configured LDAP lookup with password prefetch in DoveCot. I can successfully receive emails through DoveCot, thus proving my password prefetch and user authentication are good. The problem is when I use Postfix to deliver message to DoveCot via LDA. My postfix master.cf looks like this: dovecot

When counting required slots for skb, netback directly uses DIV_ROUND_UP to get slots required by header data. This is wrong when offset in the page of header data is not zero, and is also inconsistent with following calculation for required slot in netbk_gop_skb. In netbk_gop_skb, required slots are calculated based on offset and len in page of header data. It is possible that required slots
