applying strsplit to a whole column
I am sorry, I'd like to split my column ("names") such that all the
beginning of a string ("X..") is gone and only the rest of the text is
left.

x$names<-as.character(x$names)

how to divide a string into characters? - for comparing strings that is
Hi
I am searching for a way to do something like "ABC" -> c("A","B","C"). How can this be accomplished?
I tried cut() and split(), but they do something else, it seems.
The purpose for doing this is to find the number of common (and uncommon) characters, i.e. ultimately I want something like this:
> foo("ABD","ADE")
c(2,1) # 2

Sorting a data set
I am a novice user of R and am stumbling on how to order a dataset
produced during my session.
I have a 1863 row X 14 column dataset that I want to put out to a file.
I want the output sorted by the first column and then by the second
column both in ascending order. The first column is character and the
second is numeric (I hope). I used an "as.numeric" function to assign

Plotting contour & filled.contour in one graph

I have a question on overlaying a filled.contour (e.g. on soil properties data) and contour (by elevation) in one graph. Both have the same z matrix dimension. I'm able to overlay both graph, but the plots dimension did not overlap well on the same plots. How can I have both filled.contour and contour on the same graph?

hacer para que las dos gráficas muestren la misma escala en el eje Y, es

[Globalize] Enhancement - zip code regexes for each country
Was just playing around with trying to sort out validation of zip/postcodes
depending on what country the user lived in, and was wondering if anyone has
done this in a nice way? Seems to me that it would be a relatively simple
addition to Globalize to add a regex for zip code validation to the things
already in there?
Or am I missing a trick?
Thanks

Plotting MDS (multidimensional scaling)
Hi,
I just encountered what I thought was strange behavior in MDS. However, it
turned out that the mistake was mine. The lesson learned from my mistake is
that one should plot on a square pane when plotting results of an MDS. Not
doing so can be very misleading. Follow the example of an equilateral
triangle below to see what I mean. I hope this helps others to avoid this
kind of headache.

matrix multiplication, tensor product, block-diagonal and fast computation
Dear R-users,
I am searching to the "best" way to compute a series of n matrix
multiplications between each matrix (mXm) in an array (mXmXn), and each
column of a matrix (mXn).
Please find below an example with four possible solutions.
The first is a simple for-loop which one might avoid; the second
solution employs the tensor product but then manually selects the right
outcomes. The

try-error within for loop
Dear all,
I run a loop wrapped in try(), and for each of the rows where
"try-error" is true I want to fill that row with NA (at the moment it is
omitted). So I would expect to get a dataframe with 1000 rows some of
which would be empty, but instead I get a dataframe with 995 rows. In
this case missing 5 rows were omitted.
Any suggestions?
Thanks,
