plotDens {PBSmodelling}

Plot Density Curves from a Data Frame, Matrix, or Vector

Description

Plot the density curves from a data frame, matrix, or vector. The mean density curve of the data combined is also shown.

Usage

plotDens(file, clrs=c("blue","red","green","magenta","navy"), ...)  

Arguments

file

data frame, matrix, or vector of numeric values.

clrs

vector of colours. Patterns are repeated if the number of fields exceed the length of clrs.

...

additional arguments for plot or lines.

Details

This function is designed primarily to give greater flexibility when viewing results from the R-package BRugs. Use plotDens in conjunction with samplesHistory("*",beg=0,plot=FALSE) rather than samplesDensity which calls plotDensity.
