hello,

I have an argument of a the list a like this

> a[[18]]
[1] "C744=(C627*C177)/100"


and I wanna seperate the character and the mathematics symbol to use it like a formula
and why when I used the strsplit function i obtain as follow

> strsplit(a[[18]], '\\W')
[[1]]
[1] "C744" ""     "C627" "C177" ""     "100"

and as follow

> strsplit(a[[18]], '\\w')
[[1]]
 [1] ""   ""   ""   ""   "=(" ""   ""   ""   "*"  ""   ""   ""   ")/" ""   "" 

I don't understand why the star "*" doesn't create space between   "C627" and   "C177"
