Hello Wolfgang,
Building on Peter Dalgaard's code, are you just trying to take a sample of
a random column from each row? You don't need to use apply:
> array[cbind(1:nrow(array), sample.int(ncol(array), nrow(array),
replace=TRUE ))]
Just a general note, since you're sampling one-column-per-row
Hi José (and Rolf),
It's not entirely clear what type of 'whitespace' you're referring to,
but if you're using read.table() or read.csv() to create your
dataframe in the first place, setting 'strip.white = TRUE' will remove
leading and trailing whitespace 'from unquoted character fields

Adding an extra call to gc() (garbage collection) after writing to
clipboard will
close all unused connections (useful if a connection has been entered
incorrectly).

It was unclear if you wanted combinations (per your subject line), or
consecutive-word substrings (per your example). The code above returns
combinations.

You should review "The Recycling Rule in R" before attempting to
perform functions on 2 or more vectors of unequal lengths:

Most often, the "Recycling Rule" does exactly what the researcher

1. It's not immediately clear why you need the line "temp <- subset(df, id
== myid)"
2. The objects described by "temp$age", temp$agesmoke, and temp$yrsquit are
all vectors. So temp.yrssmoke is also a vector. This means that when you
replace, it should be with "<- temp.yrssmoke[i]", where "i" is t

We'd get a lot more people working through examples that way, and
contributors might come up with their own examples to illustrate a
particular function. A Dokuwiki site might be a place where people
could post and vote on new examples to be included in pre-existing

Hello Christofer!
For text-editing the R.app GUI has always been fabulous. An old
mainstay on the Mac (after Apple's TextEdit) has been TextWrangler,
and its big-brother, BBEdit. For development RStudio is quite nice,
and--based partly on RStudio's offering of a Vim-compatibility
mode--Vim has bec

Hi Frank,
It looks like you're very close. I think you want:
