...ordinary least square fitting and non-negativity constraints. The lm() function works well for ordinary least square fitting, but how to specify non-negativity constraints? It wouldn't make sense if the fitting coefficients coming out as negative in absorption spectra deconvolution. Thanks. Xiuli

...I have reported a bug in https://llvm.org/bugs/show_bug.cgi?id=25735, and we could not use this for now. So if there is another way to pass this memdep-block-scan-limit into the pass manager or context? Or how could I set this memdep-block-scan-limit right with libclang and libllvm?
