R programming.

 Aim: To learn about R  data types variables operators  control statements loops, r scripts Functions etc.. Data types in R: R has variety of data types such as vector, matrices, numerical, logical, character, data frames etc.. a few examples are  vector: a <- c(1,2,5.3,6,-2,4) # numeric vector b <- c("one","two","three") # character vector matrices: all columns in  a matrix must have same mode ( same charactes, same numerics) etc..  general format  : mymatrix <-  matrix( vector ,  nrow=   r ,  ncol=   c ,  byrow=   FALSE ,    dimnames=list(   char_vector_rownames ,  char_vector_colnames )) unlike other prog languages, in r we could just print the variable or value holder by just naming it without adding a print statement to print it.  > x <- 5 ## nothing printed > x ## auto-printing occurs [1] 5 > print(x) ## explicit printing [1] 5

The Advent.

 Hey all,  this would be my first post in this blog post. introductions are in order, I'm Vijay Purushoth a Pre final year engineering student pursuing computer science engineering. As of now I'm not good at anything to mention it here. so anything and everything I consume or learn (through texts, videos etc..) I'll write notes or just an explanation of what i have learned about it and post it here. mainly to mark my progress. it'd be in a way that if anyone by chance looks into it would get into a treasure trove of knowledge. I hope I'd make stellar progress in this venture soon. see y'all soon.                                                                                                              ...
