[R] plot.ts doubt

[Ernesto Jardim]

Hi,

I'm ploting a multivariate time series but I want to change the y
labels. I've tried with ylab but I get an error

> plot(hke.ts,ylab=letters[1:5])
Error in plot.ts(x[, i], axes = FALSE, xlab = "", ylab = "", log = log, 
:
        formal argument "ylab" matched by multiple actual arguments

I've tried to use xy.labels but I also get an error

> plot(hke.ts,xy.labels=letters[1:5])
Warning messages:
1: parameter "xy.labels" couldn't be set in high-level plot() function
2: parameter "xy.labels" couldn't be set in high-level plot() function
3: parameter "xy.labels" couldn't be set in high-level plot() function
4: parameter "xy.labels" couldn't be set in high-level plot() function
5: parameter "xy.labels" couldn't be set in high-level plot() function
6: parameter "xy.labels" couldn't be set in high-level plot() function
7: parameter "xy.labels" couldn't be set in high-level plot() function

What am I missing here ?
