A function as argument of another function
...y function with its argument to be
specified. Therefore
myfun(5,"2+0.3*y^2")
should return 5*(2+0.3*exp(5)^2),
myfun(5,"log(y)") should return 5*log(exp(5)) and so on.
I tried with "expression" and others, but without success. How can I solve
my problem?
Many thanks,

Error in memory.size(size) when calling R in batch mode (but not in interactive mode)
...llection, after two or three iterations, R crashes when used interactively. I thought that running and exiting R after each iteration would be the only effective way to "clean up" memory. If you have any other solutions, I would be happy to hear about them as well.

ECDF values
Dear UseRs,
maybe is a silly question: how can I get Empirical CDF
values from an object created with ecdf()?? Using
print I obtain:
Empirical CDF
Call: ecdf(t)
x[1:57] = 4.1, 4.4, 4.5, ..., 491.3,
671.27
Thanks in advance.
Regards,
Vito

CPU usage while running R code
...rently running an R program on a computer with 16 Gb memory (Windows7, 64 bit). When I look at the task manager, I see that only 4 out of the 8 CPUs are being used. Is this due to some missing in the R code, or should I change something to the settings of the computer?

partial matching with grep()

How is it possible to get this result with grep()?

formula(lm(exp(y)~exp+age, data=d))
#--> exp(y) ~ exp + age
formula(lm(exp(y)~., data=d))
#--> exp(y) ~ age
variable 'exp' (maybe indicating "experience") is not included in the
model. The same happens with 'log' (and other function names, I suppose..)

However, I definitely need to be able to run my code on the 64 version.

only actual variable names in all.names()

"y" "x" "z"
Where is the trick?
