hi, I know how to use the "for" loop function like: for(i in 1:ncol(mat)){ mat[i]<-b[i,2] } but, in this case r1<-b[1,1] r2<-b[2,1] r3<-b[3,1] r4<-b[4,1] * * * r3002<-b[3002,1] r3003<-b[3003,1] - must make vectors how should I make a efficient code for that?

Hello, The use of .Call and the like all depend on loading shared libraries and registering routines from it. Also, .Primitive and .Internal depend on routines being registered in the R binary. And applications that embed R can override routines declared in Rinterfac.h, but is there a way for an application embedding R to register other routines defined in the application without loading a

hi all: Following is simple example, for(i in 1:10000000){ a<-function(i){ #some function that has an error } } What I want to know is the way to find the error point in for-loop, What "i" makes the error. is there any way to solve it instead of debugging and finding an error manually?

hi, what I want to do is assigning following code to any object. k<-paste("thank") writeLines(strwrap(k, width = 80,indent = 7,exdent = 6)) To assign the "writeLines" code, I try this a<-writeLines(strwrap(k, width = 80,indent = 7,exdent = 6)) or assign(a,writeLines(strwrap(k, width = 80,indent = 7,exdent = 6))) but it doesn't work. is there any way to solve

hi I'm simulating some experiment by "for" function.
