rename the columns name after cbind the data

Question

merger <- cbind(as.character(Date),weather1$High,weather1$Low,weather1$Avg..High,weather1$Avg.Low,sale$Scanned.Movement[a]) 

After cbind the data, the new DF has column names automatically V1, V2...... I want rename the column by

colnames(merger)[,1] <- "Date" 

but failed. And when I use merger$V1 ,

Error in merger$V1 : $ operator is invalid for atomic vectors 

Answer 1

You can also name columns directly in the cbind call, e.g.

cbind(date=c(0,1), high=c(2,3)) 

Output:

     date high [1,]    0    2 [2,]    1    3
