Makes sense, although (re-)learning what aperm does wasn't a wasted exercise. Thanks! On 9/28/2017 1:22 PM, Jeff Newmiller wrote: > The use of aperm is unnecessary if you call array() properly. > > ms <- array(c(rep(0, 5),so,sa*m,sa), c(5, 2, 2)) [[alternative HTML version deleted]]

The use of aperm is unnecessary if you call array() properly. ms <- array(c(rep(0, 5),so,sa*m,sa), c(5, 2, 2)) -- Sent from my phone. Please excuse my brevity. On September 28, 2017 9:10:26 AM PDT, Evan Cooch wrote: >Sure -- thanks -- only took me 3-4 attempts to get

Re: [R] Boxplot, formula interface, and labels.

Another way to think of this problem. If I could get my hands on the vector of names boxplot() is creating, I could use gsub() to replace '.' with '\n'. Is there something I could run before boxplot() that would give me that vector of names which I could then pass to boxplot()? On Thu, Sep 28,

[R] Boxplot, formula interface, and labels.

I have data I'd like to plot using the formula interface to boxplot. I call boxplot like so: with(mydata, boxplot(count ~ geno * tissue)) I get a boxplot with x axis labels like "wt.kidney". I would like to change the '.' to a newline. Where is this separator configured? Thanks, -Ed

Hi John, Thanks to Jim for pointing out the file.rename() function. You can try this: # define the filename templates strIn <- "XYZW--Genesis_ABC.mp3" strOut <- "01Gen--.mp3" # create the strings "01", "02", ..., "50" v <- sapply(1:50, function(i) sprintf("%02d",i) ) # perform all the file
