[R] probelm with xlab ylab and xaxp barplot

[Abdoulaye SARR]

Hi Marc,

According to your guidance the labels are almost at the right place when adjusting mar values.

A remaining need is to have the x axis at least for the two bottom figures as date from 1981 to 2005. Do you think this is doable. Ylim is fine but how tots in this case xlim.

Best regards,

You may also have to reduce the size of the font itself, which is done via the cex* arguments to barplot() and the additional annotation functions mentioned in the prior sentence.
