I try to used R to do one-way anova. 

here is the simple code

f1<- lm (y ~ block, data=yd)

there are 8 levels of factor block, 

I also want produce multiple pairwise  comparisons for the 8 levels of block, inlcuding mean and std err for each of the 8 lelevls. It is tidious to do pair test. I looked the manuals, find no clues. any suggest?
