I'm somewhat a new user and have been trying to figure out how to repeat
rows a certain number of time based on a variable. Currently, the number of
rows is not reflective of the number of observations. To get the number of
observations (n=22 in this case), I have to multiply by the variable

I'm trying to rbind two data frames, both with the same columns names. One
of the columns is a variable with date-time and this variable is causing the
rbind to fail--giving the error
"Error in names(value[[jj]])[ri] <- nm : 'names' attribute [7568] must be
the same length as the vector [9]"

I am trying to combine two columns in a data frame into one column. Some
values in either column are missing, but not in the same row for the two
different columns. Additionally, when both columns in a row contain data,
the data are identical. I want a new column with the identical data or the

2 2"b" "b" "b"
3 3"c" "c""c"
4 4 NA "d" "d"
Thanks again!
