This is a great opportunity and I am honoured to be hosting this months T-SQL Tuesday blogging invitation. With the invitation of Steve, we have agreed to post topic on Data science. I will be receiving all of your answers…Read more ›

Writing markdown documents outside RStudio (using the usual set of packages) has benefits and struggles. Huge struggle is transforming dataframe results into markdown table, using hypens and pipes. Ugghhh… This useless functions takes R dataframe as input and prints out…Read more ›

Nothing short of wacky usage of plot() function with xspline to interpolate the points, but still a “parameter” short of Bezier’s curve. 🙂 Given two random vectors, you can generate a plot that, xspline will smooth out the plot and…Read more ›

Keeping your R code organised is not as straightforward as one might think. Just think about the libraries, variables, functions, and many more. All these objects can be defined and later rewritten, some might get obsolete during the process. This…Read more ›

When you are working with large datasets performance comes to everyone’s mind. Especially when converting datasets from one data type to another. And choosing the right method can make a huge difference. So in this case, I will be creating…Read more ›

The Mandelbrot set is a set of complex numbers  c for which the function  does not diverge to infinity when iterate from , and therefore remains bounded in absolute value. For little stretching, we can create a Mandlebrot set and draw it with image function.…Read more ›
