d which would return something like:
[1] "c:/user/Desktop/"
so that regardless of where the script is, as long as the accompanying scripts
are in the same directory, they can be easily sourced with something like:
dirX <- file.path.is.here("MasterScript.r")
source(paste(dir
ype the path every time I move it).
Any ideas?

ps. I found this on the internet but a) I couldn't understand it, and b) it
didn't work:
frame_files <- lapply(sys.frames(), function(x) x$ofile)
frame_files <- Filter(Negate(is.null), frame_files)

Hi all,
One subtlety is that the drop argument only works if you specify 2 or
more indices e.g. [i, j, ..., drop=F]; but not for a single index e.g
[i, drop=F].
Why doesn't R complain about the unused "drop=F" argument in the
single index case?
Cheers,

Thanks ...
It's good to know I'm not missing the obvious.

Dear R Helper Community!
Thank you for all your help and suggestions.
For your reference and any future person searching the archives, here is the
solution that did what I wanted it to do.
As background, my goal was to find the coefficients for the following
equation form:
y ~ c1 * x1 *
rect for these
constraints.
I have already solved the problem in another statistics
package so I know the actual solution to the coefficients. But our ultimate
goal is to do additional work in R. But so far, I have been unable to
recreate our solution in R.

(apparently).
Any suggestions appreciated.
Thanks
Stu

If no additional documents exist, then that would be good to
know also.
Any pointer or advice would be useful.
Thank you!

Patrick,
Thanks for your suggestion!
The R-Inferno was especially useful!! The first chapter had me
chuckling aloud despite the fact that I work alone.
Well worth the price!
Thanks!

y, x1, x2, and x3 are observed data.
I have a total of 6 rows of data in a data set.
Is "optim" in the stats package the right function to use?
Also, I can't quite figure out how to specify the constraints.
Thank you!

Thanks Bill,
This one will work perfectly, the others required an existing matrix
to be modified, which isn't the case (I'm using this xyz function in a
larger construct). Plus it's only a 12x12, so not too big on memory.
Thank you!

Sure, that'll work fine, thanks.
But I guess I was looking for something more similar to MatLab, I'm
really surprised R doesn't have a preset command for this (?)
Thanks again,
Stu
