[R] Howto reduce number of ticks in X, Y axis while still containing all the data

[Gundala Viswanath]

Hi

I am trying to plot 100 x 100 matrix data in a level plot.
The problem I have is that the x/y -axis label in ticks
are jumbled together. Thus I want X/Y axis to contain
10 ticks only, yet still plotting all the 100 data.

Is there a way to do it?
The code I have below doesn't work.

__BEGIN__

# Corr contains 100x100 matrix
corr <- cor(t(mat.data), method ="pearson")

# Plot them
levelplot(corr, main="PCC of Top-100 Genes",
                xlab="Gene",
                ylab="Gene",
                scale=list(y=list(tick.number=10)) # Doesn't work
                )
