...ust any negative values to zero. But runquantile's computation time proves exceedingly long for my large datasets, particularly if I set the endrule parameter to 'func'. Here is what caTools author Jarek Tuszynski says about relative speeds of various running-window functions: - runmin, runmax, runmean run at O(n) - runmean(..., alg="exact") can have worst case speed of O(n^2) for some small data vectors, but average case is still close to O(n). - runquantile and runmad run at O(n*k) - runmed - related R function runs at O(n*log(k)) The obvious altern...

...ive numbers. x = rep(-1,10) runmax(x,3) x = rep(0, 10) runmax(x,3) for 32-bit R, i got very small numbers: 2.121996e-314 for 64-bit R, i got NaN. Is it a bug in runmax? or should this be included in the documentation that runmax only for positive numbers? however, we do have a workaround -- runmin works, thus we can do y = -runmin(-x,3).

...ful to broader group, is much smaller than "caMassClass" and has fewer dependencies. Other changes include: - Adding to "caMassClass" support for reading and writing mzXML data - a standard for storing proteomics MS data. - Adding more error checking to 'runmean', 'runmin', 'runmax', 'runmad' & 'runquantile' functions - Writing 3 new functions for round-off-error free sumation: 'sum.exact', 'cumsum.exact' and 'runsum.exact'. - Added option to "runmean" function to allow use of above round-off-error f...

Hellow everyone, This code bellow will calculate average daily wind speed(measurements are taken every three hours).Any ideas how to take the Min and Max instead of average. library(Matrix) setwd("C:\\Users\\aalyaari\\Desktop\\img") listfile<-dir() long <- file("C:\\Users\\aalyaari\\Desktop\\New folder (5)\\inra.bin", "rb") A=readBin(long, integer(),
