Hi,
You can try this:
dat1<-read.table(text="
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
",sep="",header=TRUE)
dat2<-dat1[10,]
dat2<-NA
dat3<-data.frame(predict_SO2_a=c(dat1[1:9,],dat2,dat1[10:18,]))
A.K.
But don't do this with more than one column in your dataframe.

Subject: [R] Insert row in specific location between data frames
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!
