thanks a lot for ur patience and understandig, josh. ok perhaps it would be help me to change my programm by step by step. the first important thing of my programm is to caluculate the correlation of each block of a radom variable.
so i have a n bivariate random sample wich i saperate in m blocks and calculate the correlation. i designe a matrix for that. so that i watch not one n bivariate random sample, but N bivariate random sample. (its important to watch a matrix because for my powerfunction later) so i programm my correlationfunction like that N=10 n=100 m=5 k=n/m l=matrix(0,nrow=m,ncol=N) for(i in 1:N){ for(j in 1:m){ x=rnorm(n,0,0.5) y=rnorm(n,0,0.8) l l[j,i]=cor((x[(((j-1)*k)+1):(((j-1)*k)+k)]), (y[(((j-1)*k)+1):(((j-1)*k)+k)])) } } i think their is a mistake, am i right? if i watch this matrix, i don´t exactliy know which correlations are to which random sample, do i? i hope u have still time to help me. regards jethi -- View this message in context: http://r.789695.n4.nabble.com/the-function-doesn-t-work-tp2714105p2714702.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
