[R] how to get components / factors in factanal / princomp not loadings

[Bunny, lautloscrew.com]

Dear all, 

i wonder if there´s a command to obtain the actual values of a principal component or a factor (not as.factor, but factanal) .


test=princomp(USArrests, cor = TRUE)
summary(test)

just outputs, standard deviation, Prop of Variance and cumulative proportion of variance. 

test$loadings offers yet another proportion of variance scheme. why is that?  

Apart from that:

 Is there a possibily to get the component itself, i mean the linear combination that represents it vor each observation ? (Loading_i * variable_variable_i)

thx in advance, best regards
