[R] plot.cuminc

[Thyago Moraes]

Dear Friends, 
I'm using the following code for generate a Figure where the x-axis is divided in intervals of 12 months (package cmprsk).However, the same numbers also appears vertically in the top of the figure.Not sure what I'm missing to avoid this.
Thanks in advance
Thyago

plot.cuminc (fit.les, xaxt='n',axis(1,c(0,12,24,36,48,60)),xlab=('Months'), ylab='CIF',curvlab=c('Death','Competing Risk'))
