I would like to run a for loop with an index going from 0 to 499 but the following seems to miss out the first value: C <- 499 for (i in 0:C) The alternative is: C <- 500 for (i in 1:C) { #Then every time I use i, I replace it with i-1 } Is this a good way to do it or is tere a better way?

(BTW, I can live with the first incorrect comma in the output file because I can just remove it manually.) Can anyone suggest a solution?

I'm using R version 2.13.0 (2011-04-13) on Mac OS X and I get the following error message with library(arules): Loading required package: Matrix Loading required package: lattice Attaching package: 'Matrix' The following object(s) are masked from 'package:base': det Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared object

Is there any easy way I can upgrade R without losing all of my packages, when I'm using a computer (Mac) on an organisation's network which blocks the package installer?

I would like to write some data to different files. I can create the filename Day1.txt like this: filen <- paste("Day", l, ".txt", sep="") and then I'm using a For loop to write out one row of a matrix, something like this: For (j in 1:10) { cat(mat[1,j], ",", file=filen, append=TRUE) } cat("\n", file=filen, append=TRUE) but is there

...26278 676529098667 98928373 1092837363526 716172829 would become: 0 1 0 2 0 3 0 4 5 6 i.e. all 676529098667 would become 0, all 1000198767829 would become 1 etc. If I read all the values into a matrix, is there a pre-existing function that can do the recoding?

I know there's a really easy way to do this but I just can't track it down. I experimented with various apply functions but couldn't get it quite right. I have a matrix like this: 1, 16 1, 23 1, 21 1, 6 1, 25 2, 4 2, 17 2, 45 2, 11 2, 20 and I'd like to find the max value in Column 2 (or the index to the max value) grouped by the first column. So the max for Group 1, the max for

Anyone got any hints on how to make this code more efficient? An early version (which to be fair did more than this one is) ran for 330 hours and produced no output. I have a two column table, Dat, with 12,000,000 rows and I want to produce a lookup table, ltable, in a 1 dimensional matrix with one copy of each of the values in Dat: for (i in 1:nrow(Dat)) { for (j in 1:2) { #If next

I'm trying to enter a frequency table manually so that I can run a goodness of fit test (I only have the frequencies, I don't have the raw data). So for example, let's say I want to re-create the HorseKicks table: library(vcd) data(HorseKicks) str(HorseKicks) 'table' int [1:5(1d)] 109 65 22 3 1 - attr(*, "dimnames")=List of 1 ..$ nDeaths: chr [1:5]

What is the best way to write out comma separated data, as a program is running (rather than waiting to the end using write.csv)? At the moment I'm doing this, but I guess it's not the most efficient. The data is in a column in the matrix postcount, and I'm using a loop to write out each of the 100 elements. for (j in 1:100) { cat(postcount[1,j], ",", file=filename,
