Hello,
You are trying to access elements that do not exist, see the example below:
x <- 1:3
x[5] # beyond the last element
#[1] NA
dim(df)
#[1] 14509225 8
df[14509227,] # beyond nrow(df) by 2
Hope this helps,
Rui Barradas

Hi All,
I have lines in file that look like this:
df[14509227,]
SNP A1 A2 freq b se p N
1: <NA> <NA> <NA> NA NA NA NA NA
data looks like this:
head(df)
SNP A1 A2 freq b se p N
1: rs74337086 G A 0.0024460 0.1627 0.1231 0.1865 218792
2: rs76388980 G A 0.0034150 0.1451 0.1047 0.1660 218792
...
sapply(df,class)
SNP A1 A2 freq b se
"character" "character" "character" "numeric" "numeric" "numeric"
p N
"numeric" "integer"
dim(df)
[1] 14509225 8
Tried:
df=na.omit(df)
dim(df)
[1] 14509225 8
and:
library(tidyr)
d=df %>% drop_na()
dim(d)
[1] 14509225 8
Please advise,
Thanks
Ana
