[R] Insert row in specific location between data frames

[Rui Barradas]

Hello,

If you print 'topdata' and 'bottomdata' you'll see that they are not 
data.frames, they're vectors. This is because you are extracting one 
column only, which happens to be the only one.
Solution: use c().

topdata <- predict_SO2_a[1:10, ]
bottomdata <- predict_SO2_a[11:nrow(predict_SO2_a), ]
nadata <- NA
d1 <- c(topdata, nadata)
d2 <- data.frame(predict_SO2_a=c(d1, bottomdata))
d2


Hope this helps,

Rui Barradas
