plotTrace function

Plot Trace Lines from a Data Frame, Matrix, or Vector

Plot trace lines from a data frame or matrix where the first field contains x-values, and subsequent fields give y-values to be traced over x. If input is a vector, this is traced over the number of observations.

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

Arguments

• file: data frame or matrix of x and y-values, or a vector of y-values.
• clrs: vector of colours. Patterns are repeated if the number of traces (y-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 plotTrace in conjunction with samplesHistory("*",beg=0,plot=FALSE) rather than samplesHistory

which calls plotHistory.
