grdR is package that contains a method to estimate and study the drug onset time in cancer cell lines. The package includes a model to (A) create synthetic data and (B) to estimate the growth response delay (GRD) effect of a drug.

if(!require(grdR)) {
devtools::install_github("mauromiguelm/grdR")
}The package has been extensively tested and I am currently working towards documenting and publishing.
