similar to: Nested loop ok now. Thanks to you all

Hi, everyone: R is new to me. I am writing a nested loop to simulate data for t-test. The following code is wrong. The subscript is out of bounds. Could anyone tell me how to revise it? Thanks, Riddle Chin. result<-matrix(ncol=5, nrow=1000) colnames(result)<-c('N=20','N=40','N=60','N=80','N=100') for (i in 1:1000){ for (j in

I am trying to find a convenient way to control line colors when printing from a for loop using the lines command. Right now I have solved this by creating a colors vector that is refered to in the loop with index. However, the colors choosen here are just 1,2,3,4,5... I would like to get colors from the col = rainbow(x) that you can use in plot() and set the to be my number of lines (I think

I was looking at the code generated from the following c code and noticed extra loads in the inner-loop of these nested for-loops: #define DIM 8 #define UNROLL_DIM DIM typedef double InArray[DIM][DIM]; void f1( InArray c, InArray a, InArray b ) { #pragma clang loop unroll_count(UNROLL_DIM) for( int i=0;i<DIM;i++) #pragma clang loop unroll_count(UNROLL_DIM) for( int

Dear R users. I'm trying to avoid using nested loops in the following code but I'm not sure how to proceed. Any help would be greatly appreciated. With regards,Phil X = matrix(rnorm(100), 10, 10) ## Version with nested loopsresult = 0 for(m in 1:nrow(X)){ for(n in 1:ncol(X)){ if(X[m,n] != 0){ result = result + (X[m,n] / (1 + abs(m - n))) } }} ## No loop-sum(ifelse(M

Hi all, I was wondering if you can help me with the following situation: I have a data frame that includes weather station data for 30 years in the form: YEAR, MONTH, DAY, TEMP 1970, 01, 01, -15 ... 1999, 12, 31, -21 I would like to add another variable "JULIAN" that assigns the integers 1 to 365 (and 1 to 366 for leap years) for each day of a year over multiple years. Here is what

Dear R People: I'm trying to build a package and am stuck on the last part; I keep getting "there is no library".

Dear R People: Here is yet another strange problem. I'm using R in one of my classes. However, the computer lab has something called "Deep Freeze" and the students cannot save anything to the hard drive. I had R installed and things were working well. They would save their .Rdata files to disks. Now, we need to add more packages. We can't download and we can't bring

Thanks for all the emails...no need to send anymore. Very informative. I appreciate all the input. The very first email solved the problem - I needed to create the sshd account.
