Generate Log-base 10 sequence of values to be used in conjunction with axis_fun when plotting log data

Generate Log-base 10 sequence of values to be used in conjunction with axis_fun when plotting log data

# S3 method for scale.fun
log(val, type)

Arguments

val

range of values

type

major or minor

Value

a function that provides major and minor ticks with labels on a log scale

Note

see axis() and axis_fun() function

Examples

set.seed(36)
x.val=exp(rlnorm(100))
y.val=exp(rlnorm(100))

xlim.val=c(1,100)
ylim.val=c(1,5000)
plot(y.val~x.val,ylim=ylim.val,xlim=xlim.val,log="xy",yaxt="n",xaxt="n")
axis_fun(1,log.scale.fun(xlim.val,"major"),log.scale.fun(xlim.val,"minor"),log.scale.fun(xlim.val,"major"))
axis_fun(2,log.scale.fun(ylim.val,"major"),log.scale.fun(ylim.val,"minor"),log.scale.fun(ylim.val,"major"))
