Dear R users, I have a 51 by 51 matrix of p-values (named as pvalue_MA). I want to present graphically this matrix in a plot (filled contour plot) where both axes represent probabilities. I have also added a grid in this plot. I want to highlight in white the cells of the grid that represent p-values smaller than the (common) significance threshold, 0.05. The code from this plot is colored in blue (I had to copy-pasted all this code in order to reach to the plot). I suspect that the "problem" might be in the col parameter of the filled.contour function. Honestly, I cannot understand why the plot appears to be completely white!! I checked the values of my variable and it has a great range from 0 to 1. Any suggestion/ comment would really help me to move on with my project.
All the best, Loukia
