I am pretty pleased with baselines I fit to chromatograms using the runquantile() function in caTools(v1.6) when its probs parameter is set to 0.2 and its k parameter to ~1/20th of n (e.g., k ~ 225 for n ~ 4500, where n is time series length). This ignores occasional low- side outliers, and, after baseline subtraction, I can re-adjust any negative values to zero. But ru...

Hi, I am hoping some one can help me. I am learning to use C and would like to learn how to call c code in R. I have look at Writing R Extensions and I tried to copy the example on page 38 void convolve(double *a, int *na, double *b, int *nb, double *ab) { int i, j, nab = *na + *nb - 1; for(i = 0; i < nab; i++) ab[i] = 0.0; for(i = 0; i < *na; i++) for(j = 0; j <

...s" 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 free computation Jarek =====================================\==...
