Check whether a number is prime or not. Each question requires a separate R code which should be to the point and as simple as it can be. In this case K-means was a better method as it was able to cluster the various segments of the dataset. file=read.csv(“path of file”, header=T) A lot of these involve hardware, because I like hardware, but almost all involve some amount of programming. The below work implemented in R. 1. The data will work for any data set and any set of variables. 5.Follow instructions Else If we require the analysis, we have to specify which variables to include because, there are 145 variables in all, and no graph or clustering technique can deal with 145 variables at a time. However the clustering technique was quite decent because of the fact of such low noise. As a kid, you might have come across a picture of a fish and you would have been told by your kindergarten teachers or parents that this is a fish and it has some specific features associated with it like it has fins, gills, a pair of eyes, a tail and so on. The Art of R Programming: A Tour of Statistical Software Design, by Norman Matloﬀ, 2011. “Hello World” Program.
