Can package plyr also calculate the mode?
I am trying to replicate the SAS proc univariate in R. I got most of the
stats I needed for a by grouping in a data frame using:
all1 <- ddply(all,"ACT_NAME", summarise, mean=mean(COUNTS), sd=sd(COUNTS),
q25=quantile(COUNTS,.25),median=quantile(COUNTS,.50),
q75=quantile(COUNTS,.75),
q90=quantile(COUNTS,.90), q95=quantile(COUNTS,.95),
q99=quantile(COUNTS,.99) )
So I got the mean, median std dev, quantiles etc.
IS there any way I can add the mode to the mixt. Thanks ahead for any
suggestions.
