使用下面的df
,我根據group/year
的每個組合製作了每個單元的頻率表。當它們不是數字時排序行
獲得絕對和相對頻率後,我貼的值轉換爲一列Frequency
有沒有一種方法,我可以改變表後,對行的單位,讓他們降序排序基於Total
組在2016年的n
?我希望我的最終輸出沒有與n
和prop
行,只有Frequency
df <- data.frame(cbind(sample(c('Controle','Tratado'),
10, replace = T),
sample(c(2012,2016), 10, T),
c('A','B','A','B','C','D','D','A','F','A')))
colnames(df) <- c('Group', 'Year', 'Unit')
table <- df %>%
group_by(Year, Group) %>%
count(Unit) %>%
mutate(prop = prop.table(n)) %>%
bind_rows(df %>%
mutate(Group ="Total") %>%
group_by(Year, Group) %>%
count(Unit)) %>%
mutate(prop = prop.table(n))
is.num <- sapply(table, is.numeric)
table[is.num] <- lapply(table[is.num], round, 4)
table <- table %>%
mutate(Frequency = paste0(n,' (', 100*prop,'%)'))
table <- table %>%
gather(type, measurement, -Year, -Group, -Unit) %>%
unite(year_group, Year:Group, sep = ":") %>%
spread(year_group, measurement)
以下是我期待產生:
Unit type 2012:Total 2012:Tratado 2016:Controle 2016:Total 2016:Tratado
1 A Frequency 2 (66.67%) 2 (66.67%) - 2 (28.57%) 2 (100%)
2 D Frequency - - 2 (40%) 2 (28.57%) -
3 B Frequency 1 (33.33%) 1 (33.33%) 1 (20%) 1 (14.29%) -
4 C Frequency - - 1 (20%) 1 (14.29%) -
5 F Frequency - - 1 (20%) 1 (14.29%) -
