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,

Hi everyone! I have a simple question.
my data is
predict_SO2_a
1 39.793231
2 30.252578
3 32.467584
4 31.941509
5 27.908320
6 11.594137
7 9.368125
8 12.319093
9 11.558811
10 7.937192
11 11.211306
12 12.400342
13 12.393146
14 13.256160
15 10.709600
16 9.966334
17 28.850652
18 10.024405
I want to insert row which is "NA" in 10th row
that is ..
predict_SO2_a
1 39.793231
2 30.252578
3 32.467584
4 31.941509
5 27.908320
6 11.594137
7 9.368125
8 12.319093
9 11.558811
10 NA
....
and it becomes 19 rows in this data.
however, I can't do this. my scipt is following
topdata <- predict_SO2_a[1:10,]
bottomdata <- predict_SO2_a[11:nrow(predict_SO2_a),]
nadata <- data.frame(NA)
d1 <- rbind(topdata,nadata)
d2 <- rbind(d1, bottomdata)
what is my problem?!
Thank in advance!
