For summary(), yes, you can alter the way things are displayed. It's easiest to think of capturing the output from summary() in a temporary variable, then displaying that variable's value, but this could also all be done as inline code. For example,
temp <- summary(data[[5]]) print(cbind(names(temp), format(as.numeric(temp))), quote=F) Second question: calling hist() with a vector of character strings doesn't work, and arguably, it shouldn't. There's no intrinsic notion of "interval" for character strings, no sense in which you want to discretize continuous data into a set of contiguous, discrete "bins". Character strings are discrete already. So use barplot(table(data[[ ? ]])). (Can't remember which columns in your exampel would have string values.) Or temp <- table(data) and print the result however you want. - tom blackwell - u michigan medical school - ann arbor - On Wed, 19 Mar 2003 [EMAIL PROTECTED] wrote: > Some general questions. > > - Can I control the output of a function?
