Hi R-users:
When I type the following code in R, using

There is no support for 'call by reference' in the S language, and
this is intentionally, but you can use environments to imitate it, cf.
?environment. See also the R.oo package.

Dear R-helpers,
I am having following problem:

Just store them as strings in the data frame and then perform a conversion
to expressions prior to the loop:
DF <- data.frame(s = c("O[3]", "NO", "NO[2]"), stringsAsFactors = FALSE)
