I'll dig into the procmail code if needed, but if dovecot could use a different filename for such locks, then that would solve my issue. procmail has such an option, and I only need to do this for inboxes.

data frame to workspace
Is there a way to import a data frame into a workspace? I created a data frame and from my understanding, a data frame is a type of object, and that the workspace stores the current session's objects. Wondering why my data frame is not showing up...

sapply and Date objects
This is probably a dumb question, but I cannot figure it out. Why does this happen? dt <- as.Date("1954-02-01") > as.character(dt) [1] "1954-02-01" > sapply(c(dt), as.character) [1] "-5813" Thanks. FS

assign to an element of a vector
I am trying to find a way to assign values to elements of a vector that will be defined by a user. So I don't have the name of the vector and cannot hard code the assignment in advance. In the example below I have to get() the vector using its name. When I try to assign to an element I get an error: > a <- c(1,2,3) > get('a')[1] <- 0 Error: Target of assignment expands to

Getting subsets of a data frame
I was reading in the Reference Manual about Extract.data.frame. There is a list of examples of expressions using [ and [[, with the outcomes. I was puzzled by the fact that, if sw is a data frame, then sw[, 1:3] is also a data frame, but sw[, 1] is just a vector. Since R has no scalars, it must be the case that 1 and 1:1 are the same: > 1 == 1:1 [1] TRUE Then why isn't sw[,1] =

Rprofile.site not executed?
It seems that my Rprofile.site file is not executed when I start R. To test this I included the following code in that file: .First <- function(){ cat("\nWelcome at", date(), "\n") flush.console() } When I start R the message above is not displayed. I am running R 2.6.1 (rgui.exe) under Vista Home Premium. The Rprofile.site is in the etc folder and the R_PROFILE

Time series indexes
I tried to assign values to specific elements of a time series and got in trouble. The code below should be almost self-explanatory. I wanted to assign 0 to the first element of x, but instead I assigned zero to the second element of x, which is not what I wanted. Is there a function that will allow me to do this without going into index arithmetic (which would be prone to errors)? FS >
