TestHistogram_A is a function that plots a histogram, then returns 3. For me it fails
to display the plot, at least in the order given below. TestHistogram_B is a function that plots a histogram, then exits. The only difference between the 2 functions is that B does not return 3. It displays the plot. This problem does not occur when histogram is replaced by boxplot Their use is in the following statements: Data <- c(1,1,1,2,2) Data <- data.frame(Data) TestHistogram_A <- function (my.data) { histogram(my.data[,1],main="TEST"); 3} TestHistogram_A(Data) TestHistogram_B <- function (my.data) { histogram(my.data[,1],main="TEST") } TestHistogram_B(Data) [[alternative HTML version deleted]] ______________________________________________ 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.
