constructing a vector from a dataframe and another vector
...GE 0.137
and a character vector of symbols that might, for example, look like this:
syms <- c("ADBE", "AAPL", "ED", "ED", "ADBE")
>From these two data objects, I'd like to construct the following numeric
vector of dividends:
divvec <- c( .025, .025, .025, .550, .410, .550, .410, .550, .410, .025,
.025, .025)
In other words, I'd like to construct a numeric vector by replacing each
symbol in syms
by the dividends associated with that symbol in the dataframe divs.
Symbols can occur more than once in syms, and some of...

recursively divide a value to get a sequence
Hi,
if given the value of, say, 15000, I would like to be able to divide
that value recursively by, say, 5, and to get a vector of a determined
length, say 9, the last value being (set to) zero- i.e. like this:
15000 3000 600 120 24 4.8 0.96 0.192 0
These are in fact concentration values from an experiment. For my
script, I get only the starting value (here 15000), and the factor by
which
