prevent conversion to factors in aggregate?
...figure out how to prevent a column that is the result of
an aggregate function call so that I can use it in further calculations. For
example, I would like to aggregate the expf for the data.frame by sp
(character) and dbh (double d=rounded to integer) using the command:
> st2 <- aggregate( ntrs$expf, by=list(sp=ntrs$sp,dbh=ntrs$dbh), sum )
> st2$expf <- st2$x / 20
> st2$basal.area <- st2$dbh^2 * st2$expf
Warning message:
"^" not meaningful for factors in: Ops.factor(st2$dbh, 2)
>
attributes(st2$dbh) tell me the class is a factor. I would like to values to
remain...

Q re iterating a process and appending results to output file

> c <-0.05
> i <-2500
Second two commands are formulas I want to repeat many times (sort of like
an Excel/VBA macro) using those same

Question on openSSH and sending file to MVS file formats
Hello,
I was looking for Damien Miller, Markus Friedl or Theo de Raadt to
possibly answer an SFTP question. I am having trouble locating an example
and think the task can not be done.
Do you have an example of an unix host machine initiating a file transfer
to an ibm z/OS and create a mvs file?
I have examples from appendix A of the IBM Ported Tools for z?OS Users
Guide that shows how
