Hello All, Please consider the following: TotEmp<-c(19,6,1,1,8,44,2,33,48,1) ClusterType<-c("AGF","CNS","OSV","RTL","RTL","TRN","REL","ACC_CLUST","RTL","WHL") Taz<-c(0,0,0,100,100,100,101,101,102,103)
AllCtTypes_<-c("AGF","CNS","OSV","RTL","TRN","REL","ACC_CLUST","WHL","ADM_CLUST", "HLH","HLH_CLUST","ACC","RTL_CLUST","MFG","ADM","MFG_CLUST","CNS_CLUST","PRF","PUB", "FIN","INF_CLUST","INF","EDU_CLUST","REC","EDU", "MNG","UTL","MIN") #Build data frame EmpTotCt.Zn..<-data.frame(TotEmp,ClusterType,Taz) #Reverse rows to columns EmpTotCt.Zn2..<-as.data.frame(t(as.matrix(EmpTotCt.Zn..))) "EmpTotCt.Zn.." is a data frame that i would like to alter by adding new columns and input 0s where no values exist. I tried the line below as its the only way i know of switching columns to rows but its far from what i am looking for. So "EmpTotCt.Zn.." returns TotEmp ClusterType Taz 1 19 AGF 0 2 6 CNS 0 3 1 OSV 0 4 1 RTL 100 5 8 RTL 100 6 44 TRN 100 7 2 REL 101 8 33 ACC_CLUST 101 9 48 RTL 102 10 1 RTL 103 But what i want is to return the below: AGF CNS OSV RTL RTL TRN REL ACC_CLUST RTL 0 19 6 1 0 0 0 0 0 0 100 0 0 0 1 8 44 0 0 0 101 0 0 0 0 0 0 2 33 0 102 0 0 0 0 0 0 0 0 48 103 0 0 0 0 0 0 0 0 1 Where the rows represent "Taz" and the columns represent ALL "ClusterType"'s found in "AllCtTypes_", this would mean that the above output example would have many more columns with 0s in all the rows since there are no observations. Its taken me a while to get the data into the above format and im afraid im stuck with how to get it into the final computational format, so hopefully someone can help. Perhaps i have to build a blank data frame with the appropriate dimensions first but i am not sure if this is the most efficient way of accomplishing this. Thanks in advance. -- View this message in context: http://r.789695.n4.nabble.com/Data-frame-manipulation-tp2233932p2233932.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
