Extract Standards

Separates specified serial dilutions for fitting, background, and samples

extractStd(MFI, stdstr, bgstr, stddil, smpdil, antigen, fname, pdate)

`MFI`	data frame with variable "Sample" that contains information about standard concentrations in "1/dilution" format (e.g. "1/200").
`stdstr`	character string indicating standards in the file's "Sample" column. Not case sensitive. If `""` (empty string), standards will be determined by the pattern "1/" only.
`bgstr`	character string indicating background in the file's "Sample" column. Not case sensitive.
`stddil`	standard dilutions to use for standard curve fitting. If `NULL`, all the dilutions indicated in a "Sample" variable are used.
`smpdil`	single value for sample dilutions (if dilutions are not provided in `smp` data frame). Ignored if `dilvar` is provided and the variable is included in `smp` data frame.
`antigen`	character string.
`fname`	name of the file that contains raw data.
`pdate`	date of the plate processing.
