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 a dummy list, and I will convert the values in the list into data.frame. Simple function to create a large list (approx. 46MB with 250.000 elements and each element consists of 10 measurements). cre_l <- function(len,start,end){ return(round(runif(len,start,end),8)) } myl2 <- list() # 250.000 elements is approx 46Mb in Size # 2.500 elements for demo ..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. MandelBrotImage <- function(){ cols <- colorRampPalette(c("white","black","white","grey","black"))(11) n <- 400 x <- seq(-2, 1, length.out=250) y <- seq(-1.5, 1.5, length.out=250) c <- outer(x,y*1i,"+") z <- matrix(0.0, nrow=length(x), ncol=length(y ..read more
