Basic question: Reading in multiple choice question responses to a single column in data frame
I'm using read.delim to successfully read in tab delimited data, but some
columns' values are comma seperated, reflecting the fact that user chose a

basic information defining functions
Hi all,
i am looking from some insights to define own R functions. so far i

Asterisk 1.6.2.10 & CDR custom added field
Hello list,
I have added an extra field "mycolumn" to the cdr table in my MySQL-DB.

dialplan :

Pulling columns out of a data.frame
Hi there
Probably a very simple solution to this problem.

Avoiding a Loop?
Dear R-Helpers,
I have a matrix where the first column is known. The second column is
the result of multiplying this first column with a constant "const". The
third column is the result of multiplying the second column with
"const".....

nr.of.columns <- 4
myconstant <- 27.5
mymatrix <- matrix(numeric(0), nrow=5,
