Er zijn twee methoden die u kunt gebruiken om de factorniveaus in R te hernoemen:<\/span><\/p>\n

Methode 1: gebruik Base R-niveaus()<\/strong><\/span><\/p>\n

 levels(df$col_name) <- c(' new_name1<\/span> ', ' new_name2<\/span> ', ' new_name3<\/span> ')<\/strong><\/pre>\n
 Methode 2: Gebruik recode() uit het dplyr-pakket<\/strong><\/span><\/p>\n
 library<\/span> (dplyr)\n\ndata$col_name <- recode(data$col_name, name1 = ' new_name1<\/span> ', \n                                       name2 = ' new_name2<\/span> ',\n                                       name3 = ' new_name3<\/span> ')<\/b><\/span><\/span><\/pre>\n
 De volgende voorbeelden laten zien hoe u elk van deze methoden in de praktijk kunt gebruiken.<\/span><\/p>\n
 Methode 1: gebruik de functie levels().<\/strong><\/span><\/h3>\n
 Stel dat we het volgende dataframe in R hebben:<\/span><\/p>\n
 #create data frame<\/span>\ndf <- data. frame<\/span> (conf = factor(c('North', 'East', 'South', 'West')),\n                 points = c(34, 55, 41, 28))\n\n#view data frame<\/span>\ndf\n\n   conf points\n1 North 34\n2 East 55\n3 South 41\n4 West 28\n\n#view levels of 'conf' variable<\/span>\nlevels(df$conf)\n\n[1] \u201cEast\u201d \u201cNorth\u201d \u201cSouth\u201d \u201cWest\u201d<\/strong>\n<\/pre>\n
 De volgende code laat zien hoe u een factorniveau op naam kunt hernoemen met behulp van de functie levels()<\/strong> :<\/span><\/p>\n
 #rename just 'North' factor level<\/span>\nlevels(df$conf)[levels(df$conf)==' North<\/span> '] <- ' N<\/span> '\n\n#view levels of 'conf' variable<\/span>\nlevels(df$conf)\n\n[1] \u201cEast\u201d \u201cN\u201d \u201cSouth\u201d \u201cWest\u201d<\/strong>\n<\/pre>\n
 En de volgende code laat zien hoe u elk factorniveau kunt hernoemen:<\/span><\/p>\n
 #rename every factor level<\/span>\nlevels(df$conf) <- c(' N<\/span> ', ' E<\/span> ', ' S<\/span> ', ' W<\/span> ')\n\n#view levels of 'conf' variable<\/span>\nlevels(df$conf)\n\n[1] \u201cN\u201d \u201cE\u201d \u201cS\u201d \u201cW\u201d<\/strong>\n<\/pre>\n
 Voorbeeld 2: gebruik van de functie recode().<\/strong><\/span><\/h3>\n
 De volgende code laat zien hoe u de functie recode()<\/strong> van het dplyr-pakket kunt gebruiken om de naam van factorniveaus te wijzigen:<\/span><\/p>\n
 library<\/span> (dplyr)<\/span>\n\n#create data frame<\/span>\ndf <- data. frame<\/span> (conf = factor(c('North', 'East', 'South', 'West')),\n                 points = c(34, 55, 41, 28))\n\n#recode factor levels\n<\/span>df$conf <- recode(df$conf, North = ' N<\/span> ',\n                           East = ' E<\/span> ',\n                           South = ' S<\/span> ',\n                           West = ' W<\/span> ')\n\nlevels(df$conf)\n\n[1] \u201cE\u201d \u201cN\u201d \u201cS\u201d \u201cW\u201d\n<\/strong><\/pre>\n
