[R] map two names into one

[arun]

HI,

Try this:
vec1<-"GALAXY ACE S 5830"
vec2<-"S 5830 GALAXY ACE"
vec3<-"R GALAXY 5812 ACE"
 vec11<-paste(sort(unlist(strsplit(vec2," "))),collapse="_")
 vec22<-paste(sort(unlist(strsplit(vec2," "))),collapse="_")
 vec11
#[1] "5830_ACE_GALAXY_S"
 vec22
#[1] "5830_ACE_GALAXY_S"

 identical(vec11,vec22)
#[1] TRUE
 vec33<-paste(sort(unlist(strsplit(vec3," "))),collapse="_")
 identical(vec11,vec33)
#[1] FALSE

A.K.

Subject: [R] map two names into one


Dear R user:


I have got the following problem:

I have imported two data sets into R: one set includes price information, another one includes volume information. but I noticed the wrong data order problem in the product name,

for instance,

in one data set,

"GALAXY ACE S 5830"

in another one,

it is "S 5830 GALAXY ACE"  

both represent same product. how do i map two name into one in R?

there are so many product name having this problem. i hope there is some mechanism which can autimatically map those.  thanks for your help..


Kind regards,
Tammy
