Someone pointed me to this discussion by Lior Pachter of a controversial claim in biology. The statistics The statistical content has to do with a biology paper by M. Kellis, B. W. Birren, and E.S.

Base SAS contains many functions for processing strings, and you can call these functions from within a SAS/IML program. However, sometimes a SAS/IML programmer needs to process a vector of strings. No problem! You can call most Base SAS functions with a vector of parameters. I have previously written about […] The post Convert a vector to a string appeared first on The DO Loop.
