loglm {log10}R Documentation

Add a linear model to a plot

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)
