Am trying to merge about 15 .csv tables - tried a test run but came up with
0 rows (no data for each variable/column head)
> CAHSEE.EA.feb.2009<-read.csv("2009 CAHSEE EA feb 2009.csv", header=TRUE)
> CAHSEE.IM.MATH.2009<-read.csv("2009 CAHSEE Impact Math.csv", header=TRUE)
> testmerge<-merge(CAHSEE.EA.feb.2009,CAHSEE.IM.MATH.2009)
> testmerge
[1] Grade LocalStudentID MathPassed MathScaleScore SchoolCode
[6] LastName FirstName ELAPassed ELAScaleScore
MathTestDate
<0 rows> (or 0-length row.names)
I know several variables are shared in both sheets. Please advise.
