I have strings like these:

```
x <-c("DATE TODAY d. 011 + e. 0030 + r. 1061","Now or never d. 003 + e. 011 + g. 021", "Long term is long time (e. 104 to d. 10110)","Time is everything (1012) - /1072, 091A/")
```

Desired output:

```
d <- c("DATE TODAY","Now or never","Long term is long time","Time is everything")
```

After an hour with SO search, I just could not do it. Any help is appreciated.

Answer:

This bit uses `stringr`

to extract anything containing two or more alphabeticals:

```
> library(stringr)
> unlist(lapply(str_extract_all(x,"[a-zA-Z][a-zA-Z]+"),paste,collapse=" "))
[1] "DATE TODAY" "Now or never"
[3] "Long term is long time to" "Time is everything"
```

I'm hoping the "to" missing from your desired output is a mistake on your part. Its a perfectly good word, and you said you wanted to extract words.
