Hi July, You might want to check out the "moments" package. It has a couple functions, "all.moments()" and "moment()" that will compute these for you. By the way, "RSeek.org" is a great place to find packages like this...

Hello Samantha, I'm having some trouble understanding your question in terms of what's happening in R. Are these "bins" columns of a data.frame? Rows? It's helpful for us to have a small example to look at...

Even after I discovered match(), it took me a little while to figure out how to use it for this task, so to add on to Peter's comment--to add a column for total for each value of "coll...

Hi Mark, You can do this easily with the "identify" command in ImageMagick <http://www.imagemagick.org>. Install it, and then from within an R session: system2("identify", "yourimagename.jpg") ...and it should give you something like this: yourimagename.jpg...

Hi Abhilash, >From ?example, under "arguments": local: logical: if ?TRUE? evaluate locally, if ?FALSE? evaluate in the workspace. So all you need to do is: > x <- 0 > example(mean, local=TRUE) mean> x <- c(0:10, 50) mean> xm <- mean...

It's hard to see where the problem is from this information. I would suggest subscribing to and asking this question of the RExcel mailing list (accessible from http://rcom.univie.ac.at/) and providing more detail of what you...

Another possibility: dfs <- list(df1, df2, df3) df.1.2.3 <- as.data.frame(unlist(sapply(dfs, function(x) do.call(paste, x)))) On Mon, Jun 6, 2011 at 2:37 PM, Ista Zahn <izahn at psych.rochester.edu> wrote...

You're trying to write an object that you've never created. If you want to write `varHL2y`, which it appears you do, you would replace that for `mydata` in your command. Best, Ethan On Sun, May 13, 2012 at...

Hi Alison, By default, a function in R creates a copy of the variable that you pass into it. insertRow() looks to be unusual in that it actually changes the variable you pass into the function. So if you run...

Hi, this looks like a typo to me. The name of the argument to your function is 'pre.mat', but you're trying to print an object called 'pred.mat' (with an extra 'd') that never appears before. It's...

Hi Ungku, your error is in your call to lda.default; the object that you want to plot, lda_result, is thus not created and cannot be plotted. The error you're getting with LDA doesn't look to be...

Hi Simon, You'll notice the "test" data.frame has a whole mix of characters in the columns you're interested, including a "-" for missing values, and that the columns you're interested in are in fact factors. as.numeric...
