Calculates the mean, standard deviation, and number of observations in each group of a data.frame that has one continuous variable and two factors.
Usage
sufficient(x,
yname = dimnames(x)[[2]][[1]],
factor.names.keep = dimnames(x)[[2]][-c(1, 2)])Arguments
- x
data.framecontaining a continuous variable and two factors.- yname
Character name of response variable.
- factor.names.keep
Character vecotr containing the names of two factors in the
xdata.frame.
Value
Data.frame containing five columns and as many rows as are implied by
the crossing of the two factors. Each row contains the mean in a
column with the name yname and its factor values in columns
named with the name in factor.names.keep. The standard deviation of
the observations in the group are in the column "sd" and the number
of observations in the group is in the column "nobs".
