environment question: changing variables from a formula through model.frame?
...changing variables that are found through using model.frame on a
formula inside a function.
I wonder if it's a "bug" or a "feature". And in either case, how it might
be managed.
Here is a simple example:
# let's say we have an x and y variables:
temp_x <- rep(1,5)
temp_y <- c(1:5)
# we now create a function that will take a formula of y~x and will (try and
*fail* to) change "y" (only) inside the environment of this function:
foo1 <- function(formu)
{
print("Before changing the 'y' variable in the formula")
print(model.frame(formu))...

Merging data tables
Hi all,
I am trying to merge several data sets and end up with a long data
format by date & time so I can run correlations and plots. I am using
Deducer as an R GUI but can just use the R console if easier.
The data sets are weather with wind speed, relative humidity and
temperatures by date and minute and bat activity with date, time, label,
and an activity index number. The bat
