This function takes data and a list of columns from data itself, and returns only those rows from data, for which the mentioned column names in collist are not NA. I know it can be done using for loop, but I want to do it without using for loop....
It never pulls data into R unless you explicitly ask for it. It delays doing any work until the last possible moment - it collects together everything you want to do and then sends it to the database in one step. When you construct a dplyr query, you can connect multiple verbs into a single pipeline. For example, we combined the filter() and select() verbs using the %>% pipe. If we wanted to

It is easy to extract data from the rows and columns of a data frame but there are situations when we need the data frame in a format that is different from format in which we received it. R has many functions to split

  • To check whether an entire row is blank, I have used 'WorksheetFunction.CountA(Rows(r))' to compare it with zero. If there is any non-blank cell in that row, the 'CountA' wouldn’t be zero. After the loop, we would have found the first non-blank row, but it is important to check which cell in this row has a value, because we need to issues Ctrl+A on this cell to select its entire range. This
  • For data frames, the subset argument works on the rows. Note that subset will be evaluated in the data frame, so columns can be referred to (by name) as variables in the expression (see the examples).
  • Note that the Date column was originally POSIXct (Date and Time data type in R) but ‘seq.Date’ function works only for Date data type, so I’m changing it by using as.Date function. In Exploratory, you can simply run this command with Custom Command input mode .
