Subject: Re: [R] Boxplot of multiple vectors with different lengths
Bert,
I may be mistaken, but I thought Ryan wrote "write code that automatically
*imports
data* from different files (with different lengths-just one variable)", so, I
was referring to doing something with the data before it gets into R. I understand
that one should not need to write out data and then re-read it in some way. As I
said, those more experienced with R will probably offer better ideas.

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.
Cheers,

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.

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
