I have the following cost function:
cost<-function(x){
x[,1]*sin(4*x[,1])+1.1*x[,2]*sin(2*x[,2])
}
If I send in a matrix which has MORE than one row and 2 columns, this
works fine. However, if I try to do cost(t(as.matrix(c(1,1 it
gives me an index error. When I tried debugging it, I found

You are chasing ghosts of performance past, Denes. The data.frame
function causes no problems, and if it is used then the OP would not need
to presume they know the internal structure of the data frame.
See below. (I am using R3.1.2.)

a2 <- list(x = rn

Hi there,
I'm performing some propensity score matching in R, where I am using
GenMatch() to generate a weight matrix for the covariates, before plugging
that into Match(). However, I keep on getting different results each time I
run the code. I'm using int.seed and unif.seed in GenMatch, but to n
Hi, Dr. Gu,
Thank you very much for the answer. This trick works.
Another question, is there a way to change the color or the axis?
Thanks!

Suitable help may not be possible. I suspect that either your
function/code is funky (is the function smooth, non-infinite near your
starting value?) or you are overparameterized. If the latter, the
remedy may depend on the nature of your data, which you have not
shared.
While you may receive some
Dear All,
I am trying to fit the following model in nlsLM():

I recently started working with the step() function in the lmerTest package and

I tried to contact you via e-mail, but apparently it didn't work.

how is it possible that the loadings of the second or even third
