Re: [R] Return value from function with For loop

David et. al.: "this levels is the level where you realize that the `for` function is different from most other R functions. It is really a side-effect-fucntion. " for(), while(), if(), next, etc. are *not* functions. ?for says: "These are the basic control-flow constructs of the R language."

Re: [R] Return value from function with For loop

In the first case you have a "for" and it is the statement after the 'for' that is the return value and it is a NULL. For example: > print(for (i in 1:4) i+1) NULL In the second case, the last statement if the expression '(n+1)' which give you the correct value: > xx <- function(n) n+1 >

Re: [R] help on readBin in R

If the file is not too large, just change the extension to '.txt' and attach it. Also include the code that you are using to read it in and a definition of the what the data is; e.g., first two byte are temperature, next four bytes are a station ID, Here is an example of reading in a binary

In the code below *ff <- function(n){ for(i in 1:n) (i+1)}* *n<-3;ff(n)->op;print(op)* Why doesnt *print(op) * print 4 and instead prints NULL. Isnt the last line of code executed is *i+1 * and therefore that should be returned instead of NULL instead if I say *ff <- function(n){ (n+1) }*

That was aimed at Rolf... For the actual question, I think the best approach would be to follow up on Bill Dunlap's suggestion. The mails from Jeff and Henrik pretty much tell you step by step what to try to find out which files on yours system are being checked in order to find startup code.

Re: [R] the difference between "-" and "!" between base and data.table package

! is a logical operator... it means "not". When you write lidx <- seq_along( mtcars[[ 1 ]] ) %in% train_indices you end up with a vector of logical values for which ! makes sense. Since R supports logical indexing this can be a very convenient way to select one group or the other. If you
