Remove observations with missing values in R
Collection of data is a very tedious project, and in the process, a lot of data may end up missing due to errors experienced either during data input or data conversions. Due to the vast nature of datasets, it is inefficient to peruse data checking which observations were not recorded. R programming enables the user to identify missing values in the various records and observations. Once identified the user then has the privilege of editing the records or eliminating them due to inconsistency so as to achieve accuracy when performing different statistical analysis. If this is not carried out, then the mean of a particular field, for example, would be inaccurate as there are missing values yet the total number of records is used to achieve the mean.
Missing value treatment in R begins by installing the tidyr package this is achieved by a single line of code in R programming. The next line of code involves the drop_na function; this function displays records which have complete values for the stated column in the drop_na code. One can edit the columns in that are essential to be filled with complete observations, by including the name of the columns after calling the drop_na function. It is important for a y user to carry out missing value treatment in R, in order to enhance the accuracy of Data analysis.
