R help - Jul 2008 - Insert rows into a pre-existing data frame

Hi,

I'm sorry if this is a simple question. How do you insert a blank row into a
data frame? I basically need to do this:

old table:           new table:

C1  C2  C3           C1  C2  C3
1   32  34           1   32  34
2   52  23                   54
                     2   52  23

Hi "somebody"

I hope this helps:


df1<-data.frame(cbind(va=runif(3), vb=runif(3)))
df1

df2<-data.frame(cbind(va=runif(3), vb=runif(3)))
df2

df.blank<-data.frame(cbind(va=NA, vb=NA))
df.blank

df.join<-rbind(df1, df.blank, df2)
df.join
