问题描述
我正在尝试最后几个小时，以了解为什么我不能将另一个年龄组的年龄组重新分组？我正在使用R中的forecats库进行此操作。
这里是数据：
data <- structure(list(`Country code` = c(900,900,900),Type = c("World","World","World"),`Parent code` = c(0,0),year = c(2020,2020,2020),age_grps = c("0-4","05-Sep","Oct-14","15-19","20-24","25-29","30-34","35-39","40-44","45-49","50-54","55-59","60-64","65-69","70-74","75-79","80-84","85-89","90-94","95-99","100+"),value = c(" 677 942"," 664 439"," 641 267"," 612 196"," 597 388"," 594 692"," 605 531"," 544 819"," 493 789"," 479 366"," 445 773"," 387 849"," 322 142"," 269 644"," 188 677"," 123 782"," 81 930"," 42 186"," 16 680"," 4 134"," 573"
),age_groups = structure(c(1L,2L,21L,4L,5L,6L,7L,8L,9L,10L,11L,12L,13L,14L,15L,16L,17L,18L,19L,20L,3L
),.Label = c("0-4","0-9","100+","10-14"),class = "factor")),row.names = c(NA,-21L),class = c("tbl_df","tbl","data.frame"))
这是重新分类：
age_levels <- c("0-4" = "0-19","5-9" = "0-19","10-14" = "0-19","15-19" = "0-19","20-24" = "20-39","25-29" = "20-39","30-34" = "20-39","35-39" = "20-39","40-44" = "40-59","45-49" = "40-59","50-54" = "40-59","55-59" = "40-59","65+" = "60-64","65+" = "65-69","65+" = "70-74","65+" = "75-79","65+" = "80-84","65+" = "85-89","65+" = "90-94","65+" = "95-99","65+" = "100+")
这是我正在使用的代码：
data_rec <- data %>%
dplyr::mutate(age_recoded_band = forcats::fct_recode(age_groups,!!!age_levels))
