Thank you, it works for the first problem!
Yet for the second problem, how can I solve that in one dataframe
(here:
latentVariableNames),
I store the names of the according dataframes as strings, and then
want to
access the
according dataframe (here: currentName) - see below?
latentVariables <- c("Planning", "Testing", ...)
createTable <- function(latentVariableNames)
{
for (currentName in names(latentVariableNames))
... but, but, latentVariables is a name-less vector???? You didn't
give those strings any names.

NULL
If you want to iterate along a character vector, you use:
for (item in vector) {
< body of loop working on item's >
}
OR;
for (idx in seq_along(latentVariables) ) {
< operations on latentVariables[idx] >
}
(Review the basic manuals you are using to learn R.)

Dear r-helpers,
I am looking for an R-equivalent for the eval-function in javascript
which
can
interpret a string as code on runtime, thereby allowing things like
for (i in c(1:2))
{
eval(items + "i") <- read.csv(eval(filename+ i), dec=",");
}
which would execute (with filename="testfile"):
items1 <- read.csv(testfile1, dec=",");
items2 <- read.csv(testfile2, dec=",");
The way I intend to use it is to define a string list containing
names of
date.frames,
and interate this list to perform some function:
createTable <- function(latentVariableNames)
{
for (currentName in names(latentVariableNames))
{
doSomethingWith(currentName)
}
}
Would be grateful for any help!
