[Fwd: Re: How to apply functions over rows of multiple matrices]
...oughts about the particular example.
My question was a bit more general though, as I have different
functions which are applied row-wise to multiple matrices. An
example that sets all values of a row of matrix A to NA after the
first occurrence of TRUE in matrix B.
fillfrom <- function(applvec, testvec=NULL) {
if (is.null(testvec)) testvec <- applvec
if (length(testvec) != length(applvec)) {
stop("applvec and testvec have to be of same length!")
} else if(any(testvec, na.rm=TRUE)) {
applvec[min(which(testvec)) : length(applvec)] <- NA
}
applvec
}

Cut intervals (character) to numeric midpoint; regex problem
...with the head of a 499 element matrix whose column names are
now the labels trom a cut() operation, I needed to get to a vector of
midpoints to serve as the basis for plotting a calibration curve
( exp(linear predictor) vs. :

auto.arima help
I am calling auto.arima with a time series that is about 186 observations long with a frequency of 52. With some time series I get:
1:last.nonzero: result would be too long a vector
Is there something that I can do to the data to avoid this error?
Thank you.

For help in R coding
Dear all,
I am doing a project on variant calling using R.I am working on pileup file.There are 10 columns in my data frame and I want to count the number of A,C,G and T in each row for column 9.example of column 9 is given below-
.a,g,,
.t,t,,
.,c,c,
.,a,,,
.,t,t,t
.c,,g,^!.
.g,ggg.^!,
.$,,,,,.,
