[R] direct data frame entry

[Tony Plate]

easy to do it by column:

 > d <- 
data.frame(name=c("obs1name","obs2name","obs3name"),val1=c(0.2,0.4,0.6),val2=c(0.3,1.0,2.0),row.names=c("r1","r2","r3"))
 > d
        name val1 val2
r1 obs1name  0.2  0.3
r2 obs2name  0.4  1.0
r3 obs3name  0.6  2.0

(when you do it by row, you get the numbers as factors because 
c("obs1name", 0.2, 0.3) etc. are character vectors)
