Introduction to the R Language - Functions
The scoping rules for R are the main feature that make it di erent from the original S language The scoping rules determine how a value is associated with a free variable in a function R uses lexical scoping or static scoping A common alternative is dynamic scoping Related to the scoping rules is how R uses the search list to bind a value to
list of some useful R functions - Columbia University
integrate() - adaptive quadrature over a nite or in nite interval 4 Plotting plot() - generic R object plotting par() - set or query graphical parameters
Solutions to Sample Questions 1 R n
3 Suppose that f: R R is a continuous function such that lim x1 f(x) = 0; lim x1 f(x) = 0: (a) Give a precise statement of what these limits mean (b) Prove that fis bounded on R and attains either a maximum or minimum value (c) Give examples to show that fmay: (i) attain its maximum but not its in mum; (ii) attain both its maximum and
Use R to Compute Numerical Integrals
Use R to Compute Numerical Integrals In short, you may use R to nd out a numerical answer to an n-fold integral I To integrate a one-dimensional integral over a nite or in nite interval, use R function integrate For example, nd out ∫ 1 0 1 (x+1) p x dx >## define the integrated function >integrand
Chapter 10 Functions
Example 100 Consider again the function f: R R, f(x) = 4x 1 We want to know whether each element of R has a preimage Yes, it has, let us see why: we want to show that there exists xsuch that f(x) = 4x 1 = y Given y, we have the relation x= (y+ 1)=4 thus this xis indeed sent to y by f Example 101 Consider again the function g: R R, g(x
