df <- data.frame(A=c(1,2), B=c(1,1)) I have a string containing a condition for a subset function, like: conditionAsString <- paste(names(df), df[1,], sep="==", collapse=" & ") > conditionAsString > "A==1 & B==1"
Now I want to use this string in the subset call, like subset(df, conditionAsString) I do not exactly now how to combine substitute, expression, parse and so on to get what I want, which would be: subset(df, A==1 & B==1) but using the string conditionAsString.
