R Program to concatenate a vector

In this Learn by Coding example,

we are explaining how to write an R program to concatenate a vector. Here we are using a built-in function paste(), collapse() for this . Function paste() helps to concatenate vectors after converting to characters.The collapse() function helps to collapses a character vector of any length into a length 1 vector. The syntax of this method is like

paste0(…, collapse = NULL)
– where …(dots) indicates one or more R objects, to be converted to character vectors and collapse is an optional character string to separate the results

collapse(x, sep = ““, width = Inf, last =”“)

– where x is the character vector to collapse, sep is the character string to separate the term. The maximum string width before truncating is indicated by width finally, the last is the last string used to separate the last two items.

Two Machine Learning Fields

There are two sides to machine learning:

  • Practical Machine Learning: This is about querying databases, cleaning data, writing scripts to transform data and gluing algorithm and libraries together and writing custom code to squeeze reliable answers from data to satisfy difficult and ill defined questions. It’s the mess of reality.
  • Theoretical Machine Learning: This is about math and abstraction and idealized scenarios and limits and beauty and informing what is possible. It is a whole lot neater and cleaner and removed from the mess of reality.
