And sorry i am an beginner The problem (as indicated by the marks around each value) is that the variable 'b' is a vector of *characters*, not of numbers. Compare the result of x - c(2,1,1,1,1,1) x # [1] 2 1 1 1 1 1 pie(x) with the result of b - c(2,1,1,1,1,1) b # [1] 2 1 1 1 1 1 pie(b) # Error in pie(b) : 'x' values must be positive. and: typeof(x) # [1] double typeof(b) # [1] character The underlying important question is: How was the vector 'b' constructed? You clearly expect 'b' to be numeric, but it is of type character. The reason for this is what you need to find out! Hoping this helps, Ted.

Re: [R] 'x' values must be positive.
Hi, b is a character vector. Try as.numeric(b). You probably need to read some documentation about R.
