Analysis with Programming

R can perform the usual mathematical operations, below are the functions: Arithmetic +     - addition -     - subtraction *     - multiplication /     - division Trigonometry sin       - sine cos       - cosine tan       - tangent asin    - sine inverse acos     - cosine inverse atan     - tangent inverse Linear Algebra +             - element-wise addition -             - element-wise subtraction *             - element-wise multiplication /             - element-wise division %*%         - matrix multiplication t            - transpose eigen     - eigenvalues and eigenvectors solve     - inverse of matrix ginv       - generalized inverse, requires MASS package rbind     - combines vectors of observations horizontally into matrix class cbind     - combines vectors of observations vertically into matrix class Reference: Kabacoff, R.

To install a package in R, the function to be used is install.packages . Let say we want to install the  ggplot2 package, simply code this with the following: To install more than one package, utilize the concatenate function, c Note that in executing the above codes, a dialogue box will pop up asking for the CRAN-Mirror , just choose the one that's in or near your country. Now to load these packages, run And to detach these packages, run
