Hello,
I was wondering if there is an R-package to automatically calculate the IC50
value (concentration of a substrance that inhibits cell growth to 50%) for some
measurements.
kind regards,
Arne

Function dose.p in recommended package MASS.

Brian D. Ripley,
Perhaps also of interest is the `drc' package on CRAN. There's an article
in JSS describing it (probably the same as the package vignette--- haven't
checked).

Hi!
Yes, the 'drc' package can be used to obtain IC50 or any other ICx value
for several, commonly used dose-response models.
The vignette is more up-to-date than the article in JSS (which dates
back to the start of 2005).
