我已经获得了数十年来该国GDP的数据集:
## @knitr dataClean
#Prepare the text for OGD
mywordsOGD<-c("hospital number:","patient name:","general practitioner","date of procedure:","endoscopist:","2nd endoscopist:","medications:","instrument:","extent of exam:","indications:", "procedure performed:","findings:","diagnosis:")
MyOGD<-textPrep(TheOGDReportFinal$OGDReportWhole,mywordsOGD,NegEx="TRUE",Extractor="1")
我在Tableau中使用数据透视功能将年份分组为列,例如:
Country 2001 2002 2003 2004 2005
U.S 1 2 3 4 5
U.K 6 7 9 9 10
.....
如何使用大熊猫做同样的事情?
