R help - Feb 2009 - Spearman-Karber method for toxicity data

Dear all,

 

I tried help.search("karber") and RSiteSearch("karber") and
RSiteSearch("*karber*") to find whether the (trimmed) Spearman-Karber
method for LD50 evaluation in toxicity data (e.g. according to Hamilton 1977)
has been implemented in R. Or does this method feature under a different name?
Of course logit and probit are doable, but Spearman-Karber seems to me to be the
way I should go with our data.

 

Thanks for all your help,

Susanne
