My intention is to create a dataframe from this data (only rows
starting @ and not containng string "asdf"). I tried to read this data
using this code:
g <- readLines("temp.txt")
g <- grep("^@", g, value=T)
g <- gsub("[@|$|\\.|/*]", "", g)
How to put this data into a data.frame?
> read.table(textConnection(g))
V1 V2 V3 V4
1 1 ds 5 Edmp
2 8 asu 3 daf
3 8 asdala 2 asdfa
4 13 astun 11 daf
5 26 dft 3 asdf
6 31 dsfp 2 asdf
So it looks like you needed to work on your regex pattern selection
strategy, but at least the conversion to data.frame is now clear.
Perhaps:
> read.table(textConnection(g[-grep("asdf",g)]))
V1 V2 V3 V4
1 1 ds 5 Edmp
2 8 asu 3 daf
3 13 astun 11 daf
