Only label selected breaks

问题:

Due to space constraints on the axes (log-transformed) I would like to only label select breaks while displaying breaks for a continuous sequence. Of course the following results in an error:

scale_x_continuous(breaks=c(-10,0,10,20,30),labels=c(-10,0,10,30))

Error: breaks and labels have unequal lengths

Is there a method to get around this problem?

Please try:

scale_x_continuous(breaks=c(-10,0,10,20,30), labels=c(-10,0,10,"",30))
