Transpose coords #54
Description
Coords returns a matrix with thresholds in columns, and the measurement in rows.
This has always been a bit weird but is becoming problematic with pipelines where a data.frame in transposed form would be better suited.
Expected behavior
> library(dplyr)
> roc(aSAH, outcome, wfns) %>% coords()
