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?
