Question

How to change the datatype of any field in an external dataset in R?

Answer 1

Hi Anand,

Try as below -

class(dataset/dataframe$col_name) <- "data type"

For Ex: Below code would change the datatype of Sepal. Length to an integer.

data = datasets::iris

class(data$Sepal.Length) <- "integer"

Here new data type should be given that can take the domain of already existing elements in the column.

Such as Numeric -> integer/character but the reverse is not always possible.

Check the validity of the datatype and accordingly change the datatype.
