Powszechnym sposobem definiowania obserwacji jako warto\u015bci odstaj\u0105cej jest sytuacja, gdy jest ona 1,5-krotna rozst\u0119pu mi\u0119dzykwartylowego powy\u017cej trzeciego kwartyla (Q3) lub 1,5-krotna rozst\u0119pu mi\u0119dzykwartylowego poni\u017cej pierwszego kwartyla (Q1).<\/span><\/p>\n

Korzystaj\u0105c z tej definicji, mo\u017cemy wykona\u0107 nast\u0119puj\u0105ce kroki, aby utworzy\u0107 prost\u0105 funkcj\u0119 identyfikuj\u0105c\u0105 warto\u015bci odstaj\u0105ce, a nast\u0119pnie zastosowa\u0107 t\u0119 funkcj\u0119 w wielu kolumnach w ramce danych R.<\/span><\/p>\n

Krok 1: Utw\u00f3rz ramk\u0119 danych.<\/strong><\/span><\/p>\n

Zacznijmy od utworzenia ramki danych w R:<\/span><\/p>\n

 df <- data.frame(index=c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10),\n                 var1=c(4, 4, 5, 4, 3, 2, 8, 9, 4, 5),\n                 var2=c(1, 2, 4, 4, 6, 9, 7, 8, 5, 29),\n                 var3=c(9, 9, 9, 5, 5, 3, 4, 5, 11, 34))\n<\/strong><\/pre>\n
 Krok 2: Zdefiniuj funkcj\u0119 odstaj\u0105c\u0105.<\/strong><\/span><\/p>\n
 Nast\u0119pnie zdefiniujmy funkcj\u0119, kt\u00f3ra mo\u017ce zidentyfikowa\u0107 warto\u015bci odstaj\u0105ce i funkcj\u0119, kt\u00f3ra mo\u017ce nast\u0119pnie usun\u0105\u0107 warto\u015bci odstaj\u0105ce:<\/span><\/p>\n
 outliers <- function<\/span> (x) {\n\n  Q1 <- quantile(x, probs<\/span> =.25)\n  Q3 <- quantile(x, probs<\/span> =.75)\n  iqr = Q3-Q1\n\n upper_limit = Q3 + (iqr*1.5)\n lower_limit = Q1 - (iqr*1.5)\n\n x > upper_limit | x < lower_limit\n}\n\nremove_outliers <- function<\/span> (df, cols = names<\/span> (df)) {\n  for (col in<\/span> cols) {\n    df <- df[!outliers(df[[col]]),]\n  }\n  df\n}<\/strong><\/pre>\n
 Krok 3: Zastosuj funkcj\u0119 warto\u015bci odstaj\u0105cej do ramki danych.<\/strong><\/span><\/p>\n
 Na koniec zastosujmy t\u0119 funkcj\u0119 do kilku kolumn ramki danych, aby usun\u0105\u0107 warto\u015bci odstaj\u0105ce:<\/span><\/p>\n
