Help "deleting negative values in a matrix, and do statistic analysis"
Hello, york8866 wrote
Hi, John,
the code ran well.
however, somehow, the means were not calculated correctly using the
following code.
test <- read.csv("Rtestdataset.csv", as.is=T,header=T)
test <- data.frame(test)
test
rowMeans(test)
apply(test,1,function(y)mean(y>=0))
Is there anything wrong?
thanks,
Yes!!! It's mean( y[y >= 0] ) Rui Barradas -- View this message in context: http://r.789695.n4.nabble.com/Help-deleting-negative-values-in-a-matrix-and-do-statistic-analysis-tp4617792p4618267.html Sent from the R help mailing list archive at Nabble.com.
