getrmse calculates the rmse of the input 'invar' series

Description

getrmse calculates the rmse of the input invar series (defaults to 'cpue') against an input 'year' time series. This is primarily designed to generate a more feasible estimate of the intrinsic variability of a cpue time-series that may be obtained from a cpue standardization. The year variable is needed to calcualte the loess curve.

Usage

getrmse(indat, invar = "cpue", inyr = "year")

Arguments

indat	the matrix or data.frame containing both a 'year' column and an invar column (default to 'cpue')
invar	the column whose rmse is wanted; defaults to 'cpue'
inyr	the column that points to the year name

Value

a list of the rmse and the loess predicted values of the invar for each year in the time-series

Examples

## Not run: 
 year <- 1986:1995
 cpue <- c(1.2006,1.3547,1.0585,1.0846,0.9738,1.0437,0.7759,1.0532,1.284,1.3327)
 dat <- as.matrix(cbind(year,cpue))
 getrmse(dat,invar="cpue")  # should be 0.08856596
 getrmse(dat,invar="cpue")$rmse

## End(Not run)
