Hello,
I'm trying to fit a sine curve over successive temperature readings (i.e.
minimum and maximum temperature) over several days and for many locations. The
code below shows a hypothetical example of 5000 locations with 7 days of
temperature data. Not very efficient when you have many more
This works great, thanks a lot!

And since as.integer(cut(x,bins
Hello everyone,
I'm trying to construct bins for each row in a matrix. I'm using apply() in
combination with hist() to do this. Performing this binning for a 10K-by-50
matrix takes about 5 seconds, but only 0.5 seconds for a 1K-by-500 matrix. This
suggests the bottleneck is accessing rows in
