Dear list members, I want to recode a data frame but do it for several variables at the same time. I want to give all the values > or equal than 1 a value of 1 and all the remaining values (0) keep in 0.
data.frame: newdf var1 var2 var3 var4 A 1 0 4 B 3 2 1 C 0 5 1 My real data frame has several more variables. I am using the recode function from the epicalc package: > recode(vars=newdf[, 2:4], old.value= newdf[, 2:4] >= 1, new.value=1) Error en recode.default(vars = newdf[, 2:4], old.value = newdf[, 2:4] >= : objeto '.data' no encontrado I guess I am not setting the condition in a proper way.
