plotDens function

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

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

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.
