As in contour. If NULL, the function computes appropriate levels.

heat
If TRUE, a heat map is superimposed to the contour plot
col.heat
Vector of heat colors

Additional arguments to image and contour
Details
This function is a wrapper for contour, with a different method to compute
a default value for levels. If heat = TRUE, a heatmap produced by image is added to the plot.
See contour for details on parameters.

Examples
# Load data
data(AGT)
x <- as.bed.matrix(AGT.gen, AGT.fam, AGT.bim)
# Compute Genetic Relationship Matrix
K <- GRM(x)
# eigen decomposition of K
eiK <- eigen(K)
# simulate a phenotype
set.seed(1)
y <- 1 + lmm.simu(tau = 1, sigma2 = 2, eigenK = eiK)$y
# Likelihood
TAU <- seq(0.5,2.5,length=30)
S2 <- seq(1,3,length=30)
lik1 <- lmm.diago.likelihood(tau = TAU, s2 = S2, Y = y, eigenK = eiK)
lik.contour(TAU, S2, lik1, heat = TRUE, xlab = "tau", ylab = "sigma^2")
