How to add a column and assign values in R language?

In R language, there are several methods to add a column and assign values.

1. Add a column and assign values using the “$” symbol.

dataframe$new_column <- value

In this case, ‘dataframe’ is the name of the data frame where you want to add a column, ‘new_column’ is the name of the column you want to add, and ‘value’ is the value to assign to the new column.

1. Use the “[ ]” operator to add a column and assign a value:

dataframe["new_column"] <- value

In this case, ‘dataframe’ is the name of the data frame to which you want to add a column, ‘new_column’ is the name of the column you want to add, and ‘value’ is the value to assign to the new column.

1. Add columns to a data frame and assign values using the “cbind()” function.

dataframe <- cbind(dataframe, new_column = value)

In this case, “dataframe” refers to the name of the data frame where you want to add a column, “new_column” is the name of the column you want to add, and “value” is the value you want to assign to the new column.

Note: the “value” in the above methods can be a vector or a list or vector of the same length as the data frame.
