WebbFinding rowmeans in r is by the use of the rowMeans function which has the form of rowMeans (data_set) it returns the mean value of each row in the data set. It has several optional parameters including the na.rm logical parameter. This parameter tells the function whether to omit N/A values. Webbrowwise () allows you to compute on a data frame a row-at-a-time. This is most useful when a vectorised function doesn't exist. Most dplyr verbs preserve row-wise grouping. The exception is summarise () , which return a grouped_df. You can explicitly ungroup with ungroup () or as_tibble (), or convert to a grouped_df with group_by (). Usage
