Hi,
I wonder whether similarly to the very quick rowSums and colSums
functions in the base package, one could add quick functions that
calculate the min or max over rows / cols in a matrix. While
apply(x,1,min) works, I found out by profiling a program of mine that it
is rather slow for
Hello,
I'm using rJava and JRI to call R scripts from my Java code, but my

Somebody can help me please ??
Thank you very much,

See rowMins(), rowMaxs() and rowRanges() in matrixStats (on CRAN).
The matrixStats package was created for the purpose of providing such
row*/col*() methods. First the functionality is provided, then the
methods are optimized for speed and memory, e.g. vectorizing,
implementing in native code,

Dear developers,
the current implementation of hist.default() calculates 'density' (and
'intensities') as
dens - counts/(n*h)
where h has been calculated before as
h - diff(fuzzybreaks)
which results in 'fuzzy' values for the density, see e.g.
tmp -
