[R] Help in R code

[PIKAL Petr]

Well, so again, my first answer was maybe too elaborated.

0. Send your replies also to help list.
1. Do not post in HTML.
2. Send some data by using output from
dput(yourobject)
3. Prepare desired output and again show it by dput(yourresult)

I still do not understand your desired output. In first sequence you dropped words „He is“ and „he“, in second „word“ and „can be“

Did you check?
4. Check if

?strsplit together with ?"%in%" can be of some help.

test <- "he is smart and fast in his work"
> test
[1] "he is smart and fast in his work"
> unlist(strsplit(test, " "))
[1] "he"    "is"    "smart" "and"   "fast"  "in"    "his"   "work"

unlist(strsplit(test, " ")) %in% "smart"
[1] FALSE FALSE  TRUE FALSE FALSE FALSE FALSE FALSE

If the above does not work for you, you need to evaluate regular expressions.

See e.g.
?gsub

OK. Some very quick help:

1. Do not post in HTML, your mail is barely readable.
2. Send some data by using output from
dput(yourobject)
3. Instead of vaguely explaining what you want to do, prepare desired output and again show it by dput(yourresult)
4. Check if

?strsplit together with ?"%in%" can be of some help.

test <- "he is smart and fast in his work"
> test
[1] "he is smart and fast in his work"
> unlist(strsplit(test, " "))
[1] "he"    "is"    "smart" "and"   "fast"  "in"    "his"   "work"

unlist(strsplit(test, " ")) %in% "smart"
[1] FALSE FALSE  TRUE FALSE FALSE FALSE FALSE FALSE
