For example, I'm trying to write this function that converts a probability table into data.frame in R. I want the argument "na" to be the first colname of this data frame.
prop_table_to_df <- function(table, nm){
data.frame(nm = factor(names(table)), Percentage = table)
}
Suppose I call a function (sk_table, "age_group") The expected out output is this
age_group Percentage
(15,20] (15,20] 0.4518717
(20,25] (20,25] 0.3118461
(25,30] (25,30] 0.2136201
(30,35] (30,35] 0.1863965
But instead the output is
nm Percentage
(15,20] (15,20] 0.4518717
(20,25] (20,25] 0.3118461
(25,30] (25,30] 0.2136201
(30,35] (30,35] 0.1863965
How do I fix this? Apparently, in this situation, R doesn't accept string or character as an argument when wrting the function. Thanks for helping.
You'll have to add another line to do the renaming after making the data.frame. I've done that below, renaming the first column of the new df to the function input nm.
prop_table_to_df <- function(table, nm){
df = data.frame(nm = factor(names(table)), Percentage = table)
colnames(df)[1] = nm #rename first column to value of nm
return(df)
}
