Function Errors
Closure is not subsettable
Matches: object of type 'closure' is not subsettable
WHAT THIS ERROR MEANS
You tried to use [ ] or $ on a function. This usually means you forgot the parentheses to call the function, or a variable has the same name as a function.
HOW TO FIX IT
1. Add () to call the function before subsetting.
2. Check if your variable name shadows a function.
3. Make sure you assigned the result, not the function itself.
CODE EXAMPLES
BAD — THIS CAUSES THE ERROR
data[1, ] # if data is still the function, not your data frame
GOOD — CORRECT APPROACH
my_data <- read.csv("file.csv")
my_data[1, ]Still stuck?
