[R-sig-ME] Could we calculate the variance explained by each fixed variable when we use linear mixed model?

[黄茹]

     Can we calaulate the respective variance explained by each fixed
variable when we use linear mixed model?

Namely, for R code of linear mixed model: model=lmer(y~x1+x2+(1/x3),data),
x1,x2 are fixed variables, and x3 is random effect. could we compute the
variance of y explained by x1,x2, respective?
