Dear all, I had to extracts/set elements from/in a matrix. Let say I have two vectors dim1 and dim2 of indices in the respective two dimensions of a matrix: I want to extract all the corresponding elements. I the case of a nxn matrix, dim1 <- 1:n and dim2 <- 1:n would extract the diagonal. I know one way would be to use the functions 'row' and 'col', but the matrixes I

Dear R-users, I am currently facing what appears to be a strange thing (at least to my humble understanding). If I understood correctly, starting with the version 1.2.3, R memory allocation can be done dynamically, and there is no need to fiddle with the --nsize and --vsize parameter any longer... So far this everything seemed to go this way (I saw the size of my processes growing when I was

Dear all, The following causes me trouble: > a <- data.frame(2:5,3:6,4:7) > str(a) `data.frame': 4 obs. of 3 variables: $ X2.5: int 2 3 4 5 $ X3.6: int 3 4 5 6 $ X4.7: int 4 5 6 7 > str(data.matrix(a)) int [1:4, 1:3] 2 3 4 5 3 4 5 6 4 5 ... - attr(*, "dimnames")=List of 2 ..$ : chr [1:4] "1" "2" "3" "4" ..$ : chr

Dear all, I may have overlooked something but the following piece of code causes me trouble: > a_data.frame(1:4) > a X1.4 1 1 2 2 3 3 4 4 > apply(a,2,cat) 1 2 3 4Error in ans[[1]] : subscript out of bounds > apply(a,1,cat) 1234NULL Is this the fact my data.frame has only one dimension ? (and do I forget somewhere (but where ?) to specify not to 'drop'

Ben Bolstad experienced something odd while running R CMD check over a package of ours using r-devel (yesterday's fresh). He tracked down the problem to a vignette calling 'library(MASS)'.

Hi, I upgraded to R-1.6.0 and R CMD check is behaving a bit weird.

Hi again, Beside R_ParseVector()'s possible inconsistent behavior, R's handling of zero-length named elements does not seem consistent either: ``` > lst <- list() > lst[[""]] <- 1 > names(lst) [1] "" > list("" = 1) Error: attempt to use zero-length variable name ``` Should the parser be made to accept as valid what is otherwise possible

Hi Simon, Widespread errors would have caught my earlier as the way that code is using only one initialization of the embedded R, is used quite a bit, and is covered by quite a few unit tests. This is the only situation I am aware of in which an error occurs. What is a "correct context", or initial context, the code should from ? Searching for "context" in the R-exts manual

Dear all, I am looking for a way to read tiff data into R (this could be something the pixmap package users could find intersting).

Thanks for the quick response Tomas. The same error is indeed happening when trying to have a zero-length variable name in an environment. The surprising bit is then "why is this happening during parsing" (that is why are variables assigned to an environment) ? We are otherwise aware that the error is not occurring in the R console, but can be traced to a call to R_ParseVector() in

Hi there, I am interested if there is anyway to keep track of the occurrence of warning message. I know that warnings will only be printed out at the end of the program if warn=0. However I am also interested at which particular set of data does the warnings occur too. This is because I am running 1000 data, so if there are 2 or 3 data that give warnings, I would like to know which are the ones

Hi everyone, I'm translating into R some programs I worked through in Matlab to calculate the angle between two vectors (very large--like 6200 rows in each vector). In Matlab, I used a series of nested for loops, because I was calculating the angles between many pairs of vectors. I know for loops are not desirable in R code, so I was wondering if anyone could recommend a faster way to
