[R] Change names on dataset

[Joel]

Hi fellow R users.

I have a problem when i try to change the Names of the columns on a dataset:
The names of the names dataset looks like this:
toPlot

> names(toPlot)
 [1] "REPORT_20"      "REPORT_21"      "REPORT_22"      "REPORT_23"     
 [5] "REPORT_24"      "REPORT_25"      "REPORT_QREP001" "REPORT_RS010"  
 [9] "REPORT_RS011"   "REPORT_RS030"   "REPORT_RS090"   "REPORT_RS110"  
[13] "REPORT_RS120"   "REPORT_RS121"   "REPORT_RS122"   "REPORT_RS130"  
[17] "REPORT_RS131"   "REPORT_RS140"              "REPORT_RS141"  

Then I got an dataset with correspondent texts

> text
               ID                                                        
TEXT
1  REPORT_RS010_D                                               
Statusrapport
2  REPORT_RS011_D                                                    
Ifyllnad
3  REPORT_RS030_D                                                      
Export
4  REPORT_RS090_D                                                 
Uppföljning
5  REPORT_RS110_D                                                  
Guidelines
6  REPORT_RS120_D                            Korstabulering - en
gruppvariabel
7  REPORT_RS121_D               Korstabulering - jämförelse med andra
enheter 
8  REPORT_RS122_D Korstabulering- två klassvariabler och jämförelse med
andra 
9  REPORT_RS130_D                                                   
Sjukdomar
10 REPORT_RS131_D                              Sjukdomar och en
gruppvariabel 
11 REPORT_RS140_D                                                 
Operationer
12 REPORT_RS141_D                             Operationer och en
gruppvariabel

I what i want is to change the names of toPlot with the real texts so I
tried this:
names(toPlot)[names(toPlot)=="REPORT_RS140"]<-text[text$ID==paste("REPORT_RS140","_D",sep=""),2];

that gave me this strange result

> names(toPlot)
 [1] "REPORT_20"      "REPORT_21"      "REPORT_22"      "REPORT_23"     
 [5] "REPORT_24"      "REPORT_25"      "REPORT_QREP001" "REPORT_RS010"  
 [9] "REPORT_RS011"   "REPORT_RS030"   "REPORT_RS090"   "REPORT_RS110"  
[13] "REPORT_RS120"   "REPORT_RS121"   "REPORT_RS122"   "REPORT_RS130"  
[17] "REPORT_RS131"   "7"              "REPORT_RS141"  

As you can see I got the number 7 instead of the text and I dont know why.
Can anyone spot the error?
