loglm: Add a linear model to a plot

In log10: Decimal log plotting in two and three dimensions

Description

Plot the regression line of a linear model to a plot

Usage

 
loglm(mod,log='xy',range=NULL,...)

Arguments

mod	The matrix to be plotted. X and Y coordinates must be passed as rownames and colnames respectively
log	The axes to be transformed to log
range	The interval on which the regression line is to be plotted (calculated internally with the model terms if none is supplied)
...	Further arguments to be passed to addlog

Examples

 
a <- seq(from=1,to=10,by=0.1)
b <- a + abs(rnorm(length(a),0,5))
c <- 2*a + abs(rnorm(length(a),0,5))
logplot(a,b,log='xy',pch=19,ylim=c(1,100))
addlog(a,c,log='xy',pch=19,col='grey')
model <- lm(b~a)
model.2 <- lm(c~a)
loglm(model,col='red',log='xy')
loglm(model.2,col='blue',log='xy',range=c(2,8),lty=3)
