Convert long response spectra to wide form.

PSL2PSW() casts canonical long spectra rows to wide columns such as PSA.H1, PSV.H1, and SD.H1.

Usage

PSL2PSW(.x, by = "auto")

Arguments

.x

Long spectra table with columns OCID, Tn, ID, and S.

by

Metadata columns to keep as row keys. The default "auto" uses all columns except OCID, Tn, ID, and S.

Value

A wide spectra data.table.

Examples

psl <- data.table::data.table(RecordID = "R1", OCID = "H1",
                              Tn = 0.1, ID = "PSA", S = 1)
PSL2PSW(psl)
#> Key: <RecordID, Tn>
#>    RecordID    Tn PSA.H1
#>      <char> <num>  <num>
#> 1:       R1   0.1      1
