...ng link: https://www.mathworks.com/matlabcentral/answers/194708-index-a-small-matrix-in-a-larger-matrix I couldn't find anything. The above function can be seen as a "generalisation" of the "which" function as well as the function described in the following post: https://coolbutuseless.github.io/2018/04/03/finding-a-length-n-needle-in-a-haystack/ Would be possible to add such a function to base R? I am happy to work with someone from the R core team (if you wish) and suggest an implementation in C. Thank you Best regards, Morgan [[alternative HTML version deleted]]

Hi All, A twitter user, Mike fc (@coolbutuseless) mentioned today that he was surprised that repeated NAs weren't treated as a run by the rle function. Now I know why they are not. NAs represent values which could be the same or different from eachother if they were known, so from a purely conceptual standpoint there is no way to tell whethe...

Hi there, using cbind with a numeric and raw argument produces an incorrect result. I've posted some details below, kind regards, Mike. e.g. > cbind(0, as.raw(0)) [,1] [,2] [1,] 0 6.950136e-310 A longer example shows that the result is not a rounding error, is not consistent, and repeated applications get different results. > cbind(0, as.raw(1:10))
