try this:

WhereToLook = c("ultracemco.bo.openam" , "ultracemco.bo.higham"

WhereToLook = c("ultracemco.bo.openam" , "ultracemco.bo.higham"

+ "ultracemco.bo.volumeam" ,"ultracemco.bo.adjustedam")

WhatToLook = c("volume", "close")

# create pattern match

pat <- paste(WhatToLook, collapse = "|")

grep(pat, WhereToLook)

[1] 4 5# create pattern match

pat <- paste(WhatToLook, collapse = "|")

grep(pat, WhereToLook)

What is the problem that you are trying to solve?

Tell me what you want to do, not how you want to do it.

Hi again,

I am facing trouble to match a vector strings. Let say I have below

full string vector

WhereToLook = c("ultracemco.bo.openam" , "ultracemco.bo.higham"

,"ultracemco.bo.lowam" , "ultracemco.bo.closeam" ,

"ultracemco.bo.volumeam" ,"ultracemco.bo.adjustedam")

WhatToLook = c("volume", "close")

Basically I need to find the positions of WhatToLook in WhereToLook.

So my code goes as below :

Although I was expecting my code would point 5 & 4 respectively.

Appreciate if someone points as correct code for above case.

Thanks,

pmatch(tolower(colnames(WhereToLook)), WhatToLook)

integer(0)Although I was expecting my code would point 5 & 4 respectively.
