Hi together,
I found a solution to my problem that works for me and performs
reasonable well in my opinion. Instead of looping through both
datasets, I decided to replicate each row in d2 from Min_Month to
Max_Month and then use the match-function. Here is the code (I changed
the original example
Hello R-Community,
I have the following matching problem: I have two data.frames, one
with an observation every month (per company ID), and one with an
observation every quarter (per company ID; note that quarter means
fiscal quarter; therefore 1Q = Jan, Feb, Mar is not necessarily
correct and
Hi,
I have a problem with function match. I might not be using it properly?
I have two character vectors that contain a unique identifier:
gtype_prochi - (CAO1524452 CAO0966182 CAO9209719 CAO4436178
CAO3761898
CAO3529266 CAO2427148 CAO8829776 CAO2517174 CAO5371418
CAO1535943 CAO1782827
Dear Dennis,
Thanks the a[a %n% b] function worked well for me.
THanks, for the help,
Natalie

I have a matching problem that I cant solve.
mystring = xxx{XX}yy{YYY}zzz{Z} where x,X,y,Y,z,Z basiclly can
be anything, letters, digits etc. I'm only interested in the content within
each {}.
I am close but not really there yet.
library(gsubfn)
strapply(mystring,\\{[^\\}]+,, perl=F)
gives me
One option is:
strapply(mystring, \\{[^\\}]+ , function(x)gsub(\\{, , x), perl = F)

Hi R gurus
I have a matching problem that I cant solve. I have tried multiple solutions
and searched varius help-sites but I cant get it to work.
This is the problem
myexstrings = c(*AAA.AA,BBB BB,*.CCC.,**dd- d)
what I want do do is to remove any non-characters in the beginning and
everything

Well I have tried that and it's unfortuanally not the solution.
This return all the characters in the string, but I dont want the characters
after the ending non-character symbol. Only the starting characters ore of
interest.
gsub(\\W*,, myexstrings,perl=T)
[1] A B CCC ddd
Regards
this should do what you want:
myexstrings = c(*AAA.AA,BBB BB,*.CCC.,**dd- d)
a = gsub(^\\W*,, myexstrings,perl=T)
b = gsub(\\W.*, , a, perl=T)
b
[1] AAA BBB CCC dd
first one, removes any non-word characters from the beginning (as you
already figured out)
second one, removes any remaining

Here is a solution using strapply from the gsubfn package:
library(gsubfn)
strapply(myexstrings, (\\w+).*, backref = -1, simplify = c)
It matches the first string of word characters following by
anything else and then returns the first backreference in
each match, i.e. the portion within

Hi
I have this vector of strings.
MyData -
c(Test1,Test2,I(Test1^2),I(Test2^3),I(Test1.Test2^2))
where I want
Here is one way of doing it:
MyData - c(Test1,Test2,I(Test1^2),I(Test2^3),I(Test1.Test2^2))
x - gsub(^(.*\\(|)([^^)]*|.*).*, \\2, MyData)
x
[1] Test1 Test2 Test1 Test2 Test1.Test2
unique(x)
[1] Test1 Test2 Test1.Test2

I am not very skilled in the use of matching patterns so bare with me
unique(gsub(^.*\\((.+)\\^.*, \\1, MyData))
?
