Create subset using variable
I am trying to create a loop that will perform a series of analyses. I am
using geeglm from geepack, which fails if there are any null values.
Creating a subset solves this, but do not seem to be able to set the subset
dynamically based on a changing variable.
while (j <= y.num) {
strSubset = as.character(df.IV$IV[j]) #Gives column name in quotes
df.data.sub = subset(df.data, strSubset>=0)
#subset dataset is not created
# analyses on subset take place
j = j + 1
}
If I type the variable name in the formula it works, so I assume that I am
not creating the variable in...
