使用{'1': 240,'2': 60}
,您可以获得以下信息:
plyr
您会得到:
Condition = c("Crop failure","Water shortage","Lang degradation","Lack of HH Labor","Lack of income from agriculture","Lack of manure / fertilizer","Others")
Type = c(1:7)
df = data.frame(Condition,Type)
vector = c(1,1,2,3,5,4,6,7)
t = plyr::count(vector)
colnames(t) = c("Type","Freq")
df =merge(df,t)
,
- 如果您想使用
base R
,以下解决方案可能会对您有所帮助。
假设您输入的是
response <- c(1,7)
然后
status <- c("Crop failure","Others")
df <- as.data.frame(table(factor(response,labels = status),dnn = list("Status")))
可以给您类似的输出
> df
Status Freq
1 Crop failure 8
2 Water shortage 7
3 Lang degradation 2
4 Lack of HH Labor 4
5 Lack of income from agriculture 2
6 Lack of manure / fertilizer 2
7 Others 1
r <- list(1,c(1,2),3),5),4),6),7))
type = seq(1,7)
dt <- as.data.frame(t(sapply(r,function(v) sapply(type,function(k) sum(k==v)))))
colnames(M) <- paste0("type",type)
给出
> dt
type1 type2 type3 type4 type5 type6 type7
1 1 0 0 0 0 0 0
2 1 1 0 0 0 0 0
3 1 1 1 0 0 0 0
4 1 1 1 0 1 0 0
5 1 1 0 1 0 0 0
6 1 1 0 1 1 1 0
7 1 1 0 1 0 0 0
8 0 0 0 0 0 1 0
9 1 1 0 1 0 0 1
此外,每个类型条目的总和可以通过colSums
计算:
> colSums(dt)
type1 type2 type3 type4 type5 type6 type7
8 7 2 4 2 2 1
或者您可以使用match()
,即
dt <- as.data.frame(t(sapply(r,function(v) !is.na(match(type,v)))))
> dt
type1 type2 type3 type4 type5 type6 type7
1 TRUE FALSE FALSE FALSE FALSE FALSE FALSE
2 TRUE TRUE FALSE FALSE FALSE FALSE FALSE
3 TRUE TRUE TRUE FALSE FALSE FALSE FALSE
4 TRUE TRUE TRUE FALSE TRUE FALSE FALSE
5 TRUE TRUE FALSE TRUE FALSE FALSE FALSE
6 TRUE TRUE FALSE TRUE TRUE TRUE FALSE
7 TRUE TRUE FALSE TRUE FALSE FALSE FALSE
8 FALSE FALSE FALSE FALSE FALSE TRUE FALSE
9 TRUE TRUE FALSE TRUE FALSE FALSE TRUE
,
这是我解决问题的机会。我使用tidyverse,因为它为我加载了stringer和tidyr
library(tidyverse)
id <- data.frame(Code = 1:7,#Make a coding data frame so you can label the results
Cause = c("Crop failure","Land degradation","Others"),stringsAsFactors = FALSE))
data <- Book1 %>%
separate(X1,into = paste0("X",1:7),sep = ";") %>% #split the data by the ;,This induces NA that are removed later
gather(key = "drop",value = "Code") %>% #put it into 1 column to exploit R's vectorization
mutate(Code = as.integer(Code)) %>% #Make the code an integer for the join later
filter(!is.na(Code)) %>% #remove those previous NAs
group_by(Code) %>%
count() %>% # Counts
left_join(.,id) #labels
colnames(data) <- c("Code","Count","Cause")
它将在单独的行上发出警告,但是,这只是让您知道它正在用NA填充多余的单元格,我们稍后将其删除。您唯一需要更改的就是DataFrame和X1,具体取决于您为对象命名的名称。
这是我的搜索结果
Code Count Cause
<int> <int> <chr>
1 1 8 Crop failure
2 2 7 Water shortage
3 3 2 Land degradation
4 4 4 Lack of HH Labor
5 5 2 Lack of income from agriculture
6 6 2 Lack of manure / fertilizer
7 7 1 Others
希望有帮助!
