Is there a variable I can set on the make install step to cause the R files to be

Hello:
Why is deriv3() functioning differently in R from that in Splus
using library(MASS) ? For example
deriv3(~(t1*log(t2)+lgamma(t1)+(1-t1)*log(y)+y/t2),c(t1,t2),function(y,t1,t2)NULL)
complains of lgamma.

Because it is not the same code. In R, the set of known functions is
hard-coded. In S-PLUS, it is extensible, and was extended by MASS (now
incorporated into the standard distribution).

You need to (re-)read ?ifelse. In ifelse(L, v1, v2), L is suppose to be a

are vectors of same length as L; i.e., ifelse() vectorizes if ... else
In the first case:
r = ifelse(length(c())!=0, c(), c(1,2))
ifelse() has three arguments, named 'test', 'yes', and 'no'.
In both of your two examples, you gave it a test argument of length equal to 1.
That is, both
length(c())!=0

length(c())==0
are expressions which when evaluated have length equal to 1.

Hi all,

Dear list,
I'm migrating a project from Matlab to R, and I'm
facing a relatively complicated problem for nls. My
objective function is below:

yTh - pdfDY(xEx,tEx,gamma,theta,kappa)
sum(log(yEx/yTh)^2)

The equation is

I'm using the new irts class from package tseries which I find quite useful.
However, I have data of different type being sample at irregular times (i.e.
my data is more of a data frame than a matrix).
Function irts that is used to create irts objects demands that the value

Is it correct that
