Searching for Enumerated Items using str_count() from the stringr package
Hi all,
I have a large number of text strings to search for enumerated items.
However, I am receiving this error message even though I thought that I
properly escaped the special character closed parenthesis:
> Count<-str_count(text3,keywords)
Error in stri_count_regex(string, pattern, opts_regex = opts(pattern)) :
Syntax error in regexp pattern. (U_REGEX_RULE_SYNTAX)
===
Here is example code:
text1<-"This is a list:
1) Number 1
2) Etc
3) Etc"
text2<-"This is NOT a list:
Blah, blah, blah

str_count counts the substring
I am trying to count the number of times a word occurs in a string.
and using str_count function from the package stringr. This function counts
the substrings as well.
Is there a way in which I can exclude the substring count and just take the
exact match.
Thanks in advance.

Thanks and Regards

stringr 0.5
...function which gives `strwrap` output in a more convenient
format
* new `word` function extract words from a string given user defined
separator (thanks to suggestion by David Cooper)
* `str_locate` now returns consistent type when matching empty string (thanks
to Stavros Macrakis)
* new `str_count` counts number of matches in a string.
* `str_pad` and `str_trim` receive performance tweaks - for large vectors this
should give at least a two order of magnitude speed up
* str_length returns NA for invalid multibyte strings
* fix small bug in internal `recyclable` function

Working with string
Hello again,
Let say I have following string:
Vec <- c("sada", "asdsa", "sa")
Now I want to make each element of this vector with equal length.
Basically I want following vector:
c("sada ", "asdsa", "sa ")
Therefore we can get:
> nchar(c("sada ", "asdsa", "sa "))

Counting the occurences of a charater within a string
I am new to R but am experienced SAS user and I was hoping to get some help on counting the occurrences of a character within a string at a row level.
My dataframe, x, is structured as below:
Col1
abc/def
ghi/jkl/mno
I found this code on the board but it counts all occurrences of "/" in the dataframe.
chr.pos <- which(unlist(strsplit(x,NULL))=='/')
chr.count <-
