...unctions to make the code more readable and ensure that every frame is done the same way. However my simple example doesn't work as I expected it to: Here the R example code to cut and paste. The basic idea is to copy positive values of y into p and negative values into l. <START COPY> AddCols = function (MyFrame) { MyFrame$p<-0 MyFrame$l<-0 return(MyFrame) } BinPosNeg = function (MyFrame) { ifelse(MyFrame$y>0, MyFrame$p<-MyFrame$y, MyFrame$l<MyFrame$y) return(MyFrame) } F1 <- data.frame(x=1:10, y=-4:5) F1 F1 <- AddCols(F1) F1 F1 <- BinPosNeg(F1) F1 &lt...

Any and all inputs appreciated on what I'm doing wrong. Thanks, Mark AddCols = function (MyFrame) { MyFrame$p<-0 MyFrame$l<-0 MyFrame$pc<-0 MyFrame$lc<-0 return(MyFrame) } BinPosNeg = function (MyFrame) { ## Positive y in p column, negative y in l column pos <- MyFrame$y > 0 MyFrame$p[pos] <- MyFrame$y[pos] MyFrame$l[!pos] <- MyFrame$y[!po...

...e function, in the sense I can create tempt1[1:7] and the max function returns what I expect. How do I do this with row? Simple example attached. hp should be 'highest p', ll should be 'lowest l'. I get an error message "Error in 1:row : NA/NaN argument" Thanks, Mark AddCols = function (MyFrame) { MyFrame$p<-0 MyFrame$l<-0 MyFrame$pc<-0 MyFrame$lc<-0 MyFrame$pwin<-0 MyFrame$hp<-0 MyFrame$ll<-0 return(MyFrame) } BinPosNeg = function (MyFrame) { ## Positive y in p column, negative y in l column pos <- MyFrame$y > 0 MyFrame$p[pos] &...

...s I have to include something more? or modify the script? -should I compile from SHLIB with other options or include it directly into a package and cretae a makevars or PACKAGE_LIBS...? I'm lost... The subroutine I try to use is delcols.f (http://www.maths.manchester.ac.uk/~clucas/updating/addcols.f) which calls * .. External Subroutines ..
