adding variables to a data set/combining two data sets
...other table. This second
table also includes a variable called dacode and I have also used dacode for
the rownames. I want to pull a number of the variables from the
socioeconomic status data into the first table but I'm having no luck.
Here's what I have tried so far:
#first attempt
grade6DA$ses1 <- sesdata$ses1[as.character(grade6DA$dacode)]
All that this does is create a new column in the grade6DA data set and calls
it ses1 but then fills it with NA.
#second attempt
grade6DA$ses1 <- sesdata$ses1[grade6DA$dacode]
Neither approach has worked so I've ended up combini...
