Hi,
I guess there should be missing values.
set.seed(5)
data1<-data.frame(commNo=sample(786:789,10,replace=TRUE),Col2=rnorm(10,10))
set.seed(5)
data2<-data.frame(commNo=sample(c(786:789,NA),10,replace=TRUE),Col2=rnorm(10,10))
data1[data1$commNo==786, "commNo"]<-"Name of the Community"
data2[data2$commNo==786, "commNo"]<-"Name of the Community"
#Error in `[<-.data.frame`(`*tmp*`, data2$commNo == 786, "commNo", value = "Name of the Community") :
?# missing values are not allowed in subscripted assignments of data frames
?head(data1,3)
#???????????????? commNo???? Col2
#1 Name of the Community 9.397092
#2?????????????????? 788 9.527834
#3?????????????????? 789 9.364629
?data3<-data2[complete.cases(data2),]
data3[data3$commNo==786, "commNo"]<-"Name of the Community"
?head(data3,4)
?# ?????????????? commNo????? Col2

#2?????????????????? 789? 9.527834

Subject: [R] missing values are not allowed in subscripted assignments of data frames
Hello everybody!
I am trying to replace community numbers with? community names (character).
I am using the following code:
data[data$commNo==786, "commNo"]<-"Name of the Community"
Unfortunately, I get the error message
missing values are not allowed in subscripted assignments of data frames
However, when I check data$commNo with table(useNA="always") or with
table(is.na(data$commNo)) it tells me that there are no NA's at all... ?
Can anyone help please?
Thank you very much!
David
