I'm looking for an easy possibility for pattern search. I have got a
string and a special pattern. I would like to know if the pattern
appears in the string, if yes where does it appear (position) and the
number of appearance.
Text = c("If the sun shines, no clouds should be seen in the sky!")
SearchPattern = c("the")
NumberOfAppearance = 0
NumberOfLetters = 0
--> NumberOfAppearance should be 2 in the end
How can I get the string length (=number of letters stored in Text)?
Has anyone a good idea?
