Data frame challenge [🇷 for BE/BA]
Dear zizou,
Thanks. Actually, what I have are vectors of times for plasma samples, and vectors with corresponding concentrations. Can use that to extract a bunch of info, including AUCt and Cmax and much else.
Sometimes unquantified (unquantifiable) concentrations for a variety of reasons are marked like "BLQ", "BLQ/2", "?", "???", "NA", "Missing", "M", "Note", "UNQ", and any other variation you can think of in English, German, Swahili, French, Inuit and 56 other languages.
I may be exaggerating ever so slightly, what I am trying to say is that it is a wee bit open-ended with those non-numeric strings.
❝ If you expect numeric values with some text known before you can use:
❝ A=read.table("SomeFile.csv", colClasses="numeric", na.strings=c("Banana","Apple"), header=T)
