pes {CFAssay} | R Documentation |
The function calculates plating efficiencies, i.e. fractions of colonies per cell of untreated cells, for every experimental replicate in a data frame with one specified curve. For that, lines with zero dose (dose = 0) are extracted from the data frame.
pes(X)
X |
A data frame which contains columns |
In the data frame X
, Exp
identifies the experimental replicates and may be numeric or non-numeric.
The function returns a data frame with three columns Exp
, pe
and S0
, containing experiment identifiers (biological replicates), measured plating efficiencies and plating efficiencies fitted separately for each repeated experiments. Rows of the data frame are named for the different experiments.
