Hello,
I'm attempting to write a code that automatically imports data from
different files (with different lengths-just one variable) and makes tidy
box plots for comparison. I can successfully import the data and create a
list of the vectors I want to compare. But I cannot, for the life of me,
figure out how to generate box plots using the "list" option. Suppose
these
are my data:
a<-c(1,1,1,1,2,3,2,1,2,3)
b<-c(2,2,2,3,4,4,4,3,3)
c<-c(4,3,3,2,3,4,5,3,3,3,4,4,5,6,3,2)
And this is my list of the vectors I'm interested in:
z<-list(c("a","b","c"))
Well, this successfully generates the kind of boxplot I want:
boxplot(a,b,c)
But this does not:
boxplot(z)
Because I'm trying to write an automatic plot-generator as the amount of
data I'm working with will typically vary, I need to write this to handle
any number of data vectors.
I've tried every imaginable means of tweaking the name of "z",
with zero
success. And I've scoured the help pages for about 45 minutes (just to
preempt any "read the help" responses). Please help!
Thanks,
Ryan

You've made a list with a single element containing three characters:> z[[1]] [1] "a" "b" "c" You need instead: z <- list(a, b, c) Also, don't call a variable c - that's a built-in function and using the name elsewhere can cause all kinds of problems (look at your own code line, where you use c as a function and as a variable. although that wasn't a problem here).

Ryan, I think you could do what you want by having the vector data written to separate files; then create a file containing the individual file names. In R, read the file containing the list of file names and loop through this reading in the individual vector files. Maybe this is an inelegant, brute force approach, but it has worked for me with essentially the same problem.

Sorry -- previous versiuon prematurely sent. Full version is: Yikes! ?You should never have to do this sort of thing (writing stuff out to files, etc.) What is wanted, I believe, is ?do.call as in do.call(boxplot, z) where z is list(a,b,c) ? as Sarah described. However, I think you might do even better in terms of controlling options, labels, etc. if you would get the data into standard flat file format (data frame) as Result Source 1 a 3 b 2 b 5 c ... etc. (This is easy to do in R and via many packages.) and then use he formula interface in the lattice ?bwplot function for th eplot.

[R] Boxplot of multiple vectors with different lengths
Ryan,
Do you necessarily have to use "list"? Have you tried the usecols=TRUE
option in boxplot?
Cheers,
