In this example, we use thedcast()function to reshape our data. That is, we can usedcast()to order our data rows according to specific variables. Table 5 reveals the output of the previous R programming syntax – Before, the data was ordered astime,feature,ID. Now it is ordered asID,...
When you have a text file with data that you would like to use in your R programming session, you will probably be able to use either the read.table function or the read.fwf function. The read.table function is designed for data with a clear delimiter, or separator, between fields, suc...
For this task, we can use the shift function like this: data[, lag1:=x1*shift(x2)]# Use previous rowdata# Print updated data The output of the previous R programming code is illustrated in Table 2 – We have created a new data.table column called lag1 that contains the values of ...
R has a data manipulation package calleddata.table()which is extensively used for data manipulation. Specially the package is very useful as a data cleaning tool for big data. Thedata.tablepackage comes with a function calledfreadwhich is a very efficient and speedy function for reading data fr...
