Hi, Sorry to bother you guys with this syntax problem, this is my first R program, and I seem to not have grasped something right. I keep getting an error message from 'parse' on the line with the *** : pValCalculator(b, n=20, m=20) { ind <- 1:min(c(n,m)) prob <- (1-pnorm(b,sd=std*sqrt(ind))) prob1 <- sum((n-ind+1)*(m-ind+1)*prob) prob1 } inputData <- scan("/users/lvssso/projects/LAMA/output/pValLamaScore.tmp", list(block1 = "",block2 = "",width1 = 0,width2 = 0,alignment = 0,score = 0)); pVal <- vector(mode = "numeric", length(lamaScore)); for(i in 1:length(inputData$lamaScore) ***** pVal[i] <- pValCalculator(inputData$score, inputData$width1, inputData$width2); inputData$pValue <- list(pVal); write.table(inputData, file = "pValLamaScore.out", row.names = FALSE, col.names = FALSE, sep = "\t"); Thanks, Shai -- Shai Shen-Orr Crown Human Genome Center and Bioinformatics Unit, Weizmann Institute of Science Home page and more contact info: http://bioinfo.weizmann.ac.il/~lvssso -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
