In this section we will see different topics on R data handling. Lets get started Get Last value of each group in R Get First value of each group in R Groupby Count in R Groupby maximum in R Groupby minimum in R Groupby mean in R Groupby sum in R Sort the column of dataframe in R String split of the column in R Repeat the string of the column in R String pad to the column in R Add Space to the column in R Set difference of dataframes in R Get the List of column names of dataframe in R Get the list of columns and its datatype in R Rename the column in R Replace the missing value of column in R Replace the character column of dataframe in R Convert to Title case in R dataframe column Convert to lower case in R dataframe column Convert to upper case in R dataframe column Position of pattern matches in R dataframe column Count the number of pattern matches in R dataframe column Extract substring of the column in R dataframe Get count of missing values of column in R dataframe Convert column to categorical in R Drop rows with missing values in R (Drop null values – NA,NaN) Percentage of the column in R Natural Log and Log of the column in R Harmonic Mean in R (Harmonic mean of column in R) Geometric Mean in R (Geometric mean of column in R) Scaling or Normalizing the column in R Get Variance of a column in R Get Standard deviation of a column in R Get Median of a column in R Get Mean of a column in R Get Maximum value of a column in R Get Minimum value of a column in R Filtering with multiple conditions in R Descriptive or summary statistics in R Re order or Rearrange the column of dataframe in R Reverse the column order of the dataframe in R Reverse the order of dataframe row wise Cube root of the column in R nth root of the column in R Square root of the column in R Cube of the column in R Square of the column in R Raised Power of the column in R Row wise mean – row mean in R dataframe Row wise sum – row sum in R dataframe Cumulative percentage of a column in R Generate Row number to the dataframe in R Rounding off the column in R Cumulative product of a column in R Cumulative sum of a column in R Stratified Random Sampling in R – Dataframe Simple Random Sampling in R – Dataframe , vector Strip Leading, Trailing spaces of column in R (remove Space) Concatenate two columns of dataframe in R Get String length of the column in R dataframe Delete or Drop rows in R with conditions Exponential of the column in R Author Sridhar Venkatachalam With close to 10 years on Experience in data science and machine learning Have extensively worked on programming languages like R, Python (Pandas), SAS, Pyspark.
