Do computations over some factors

Description

Do computations for several variables for some specific factors.

Usage

docomp(dfr, do, vars, factors, keep = NULL, method = c("fast", "slow"))

Arguments

`dfr`	The name of the data frame.
`do`	The computation to perform. Implemented options are `count`, `mode`, and standard functions like `mean`, `median`, `min`, `max`, `sd`, `var`, `sum`, etc.
`vars`	The names of the columns for the variables.
`factors`	The names of the columns for the factors.
`keep`	The names of additional columns to keep.
`method`	Use `fast` or `slow` method.

Details

This function do a specific computation for all the vars for each level's combination of the factors. Additional columns can be kept if specified in keep. All factors and keep values are converted to character. do = "count" counts the number of valid cases (excluding missing values).

Value

It returns a data frame with the computations.

Examples

# Compute means across replications and then across locations for each genotype
vars <- c("rytha", "bc", "dm", "star", "nocr")
factors <- c("geno", "loc")
output1 <- docomp(spg, "mean", vars, factors)
docomp("mean", vars, "geno", dfr = output1) 
# Compute maxima across replications for each genotype and location.
docomp(spg, "max", vars, factors)
