A quick workaround to have a filled.contour plot with natural log10-log10 scale (instead of the default natural log scale)
plotmat <- function(mat,main='',factor='M',MeasuredResponse='Coexistence')
{
X <- as.numeric(rownames(mat))
Y <- as.numeric(colnames(mat))
if(factor=='C')
{
Y <- Y/0.16
}
rownames(mat) <- as.numeric(X)
colnames(mat) <- as.numeric(Y)
colorFun <- colorRampPalette(c("black","darkblue","blue","green",
"orange",'yellow',"red","darkred",'white'))
