Get information about data tables.
Reads from files and finds the extreme values in each of the columns. It recognizes NaNs and will print warnings if the number of columns vary from record to record. As an option, it will find the extent of the first n columns rounded up and down to the nearest multiple of the supplied increments. By default, this output will be in the form -Rw/e/s/n, or the output will be in column form for as many columns as there are increments provided. The T option will provide a -Tzmin/zmax/dz string for makecpt.
