[R] map two names into one

[arun]

HI,

A small modification of my earlier approach as it creates a problem for "Glaxy ace..."

Use:
fun1<-function(x){
  res<-ifelse(grepl("\\sG",x),x,gsub("(.*)(G)","\\1 \\2",x))
  res2<-paste(sort(unlist(strsplit(res," "))),collapse= "") # collapse=""
 res2}

 vec6<-"Glaxy ace S 5830"
 vec7<-"S 5830 Glaxy ace"
vec1<-"Iphone 4S 16 G"
  vec2<-"4S G 16 Iphone"
  vec3<-"16 G Iphone 4S"
 vec4<-"3S G 16 Iphone"
 vec5<-"Iphone 4S 16G"

fun1(vec6)
#[1] "5830aceGlaxyS"
 fun1(vec7)
#[1] "5830aceGlaxyS"
 fun1(vec1)
#[1] "164SGIphone"
 fun1(vec2)
#[1] "164SGIphone"
 fun1(vec3)
#[1] "164SGIphone"
 fun1(vec4)
#[1] "163SGIphone"
 fun1(vec5)
#[1] "164SGIphone"
 fun1(vec6)
#[1] "5830aceGlaxyS"
 identical(fun1(vec6),fun1(vec7))
#[1] TRUE
 identical(fun1(vec5),fun1(vec1))
#[1] TRUE
 identical(fun1(vec1),fun1(vec4))
#[1] FALSE


A.K.

Thanks.

Yes. Your approach can identify:
Glaxy ace S 5830  and
S 5830 Glaxy ace

But you can not identify using same program:

Iphone 4S 16 G
Iphone 4S 16G

How should I solve both in same time.

Kind regards,
Tammy
