Look at the help docs and examples for textcat and sapply:
print(as.character(data$x[sapply(data$x, textcat)=="english"]))
Although textcat defaults classify "This book is amazing" as dutch, so
you may want to read the help for textcat and change the profile db
("p") or "method".

Hi all,
How is it possible to subset English text from a df containing German and
English texts using textcat package?
> library(textcat)
> dput(data)
structure(list(x = structure(c(2L, 6L, 5L, 3L, 1L, 4L), .Label = c("Dieses Buch
ist erstaunlich",
"I love this book", "ich liebe dieses Buch", "mehrere bücher in prozess",
"several books in proccess", "This book is amazing"), class = "factor")),
row.names = c(NA,
-6L), class = "data.frame")
I want the output to be like the following:
"I love this book" "This book is amazing" "several books in proccess"
Thanks for any help!
Elahe
