[R] modEvA D-squared for gamma glm

I am running a generalized linear model with gamma distribution in R (glm,
family=gamma ) for my data (gene expression as response variable and few
predictors). I want to calculate r-squared for this model.
I have been reading online about it and found there are multiple formulas
for calculating R2 (psuedo) for glm (in R) with gaussian (r2 from linear
model), logistic regression (1-deviance/null deviance), poisson
distribution (using pR2 in pscl package, D-squared value from modEvA R
package). But I could not find anything specific to gamma distributions.
Can pscl and modEVA packages be used for gamma distributions as well? or
there is any other formula for doing the same?
