R频率表图y轴对数刻度

Question

Is there any option such as log='y' when plotting frequency table. My code is as following:

df = read.table(myfile, header=F, sep=',')
freq = table(df[[1]]) # make frequency table for the first column
plot(freq, log='y')

However it cannot display logarithm. The error message is :

Warning messages:
1: In plot.window(...) :
  nonfinite axis limits [GScale(-inf,7.0814,2, .); log=1]
2: In axis(...) : "log" is not a graphical parameter

Thanks!

也许您想做这样的事情：

plot(as.numeric(names(freq)),as.numeric(freq),log='y',xlab='',ylab='freq')
