R: Makes pictures of data with growth models

picGrow

R Documentation

Makes pictures of data with growth models

Description

Takes the data file and a growth object and shows the model fit over the data.

Usage

picGrow(dataf, growObj, mainTitle = "Growth",...)

Arguments

`dataf`	a dataframe with columns ‘size’ and ‘sizeNext’(‘size’ is continuous stage variable at t, ‘sizeNext’ is stage variable at t+1); facultatively, dataf may include ‘covariate’ and ‘covariateNext’ for a single discrete covariate, indicating values at t, and at t+1, respectively; these must take values of sequential integers, starting at ‘1’. For models fitting growth increment, 'incr' or 'logincr' may be directly provided as a column in the dataframe, otherwise they are calculated as dataf$sizeNext-dataf$size or log(dataf$sizeNext - dataf$size), respectively.
`growObj`	an object of class growthObj that contains a fit for which R has methods for the function "predict".
`mainTitle`	a character string that will be used as in the ‘main’ argument of plot. Defaults to ‘Growth’.
`...`	other arguments to `plot`

Details

Note that this model will only work with growth objects that contain objects of class glm or lm, i.e. ones for which R has defined methods for the function "predict".

Value

Returns nothing.
