yearZero - examine listed variables for zeros and NAs

Description

yearZero - examines an input data.frame of matrix in the variables listed in the parameter 'label' and counts the zeros, NAs, and those >0. It counts these relative to a 'Year' variable, or any grouping variable identified using the 'years' parameter.

Usage

yearZero(indat, years = "Year", label = c("catch_kg", "Effort"))

Arguments

indat	the data.frame or matrix to be examined
years	the grouping variable for counts to be compared across, defaults to 'Year'
label	the collection of column names which are to be examined, defaults to c('catch_kg','Effort'), which is suitable for SESSF data sets.#'

Value

A matrix of the variables in 'label' with a column for each of Zeros, >0, and NAs, with a final column of the number of records per grouping variable value.

Examples

## Not run: 
 insps <- matrix(runif(30),nrow=15,ncol=2)
 insps[trunc(runif(7)*30)+1] <- 0
 insps[trunc(runif(7)*30)+1] <- NA
 insps <- cbind(sort(rep(2000:2004,3)),insps)
 colnames(insps) <- c("Year","catch_kg","Effort")
 print(round(insps,4))
 yearZero(insps)

## End(Not run)
