Well, the code did not work because you did not provide example data
and forgot that levelplot is lattice, but when I add these two lines,
it works for me. Scaling is 20,40,..., and all point are shown (hope so,
I did not count).

library(lattice)
mat.data = matrix(rnorm(100*100),nrow=100)
# 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
)
