[英]count independent values in different columns in a data frame in R
I have a data frame with several different columns and I want to get the frequency of different variables, check how the frequency of data changes depending on a parameter or two and compare the changes from the known or available ids
to the missing ids
where I have NA
.我有一个包含几个不同列的数据框,我想获取不同变量的频率,检查数据频率如何根据一个或两个参数变化,并将已知或可用
ids
的变化与我拥有的缺失ids
进行比较NA
。
The objects Id
is always known but there are cases where rq_ind
is missing and those are interesting.对象
Id
始终是已知的,但在某些情况下rq_ind
丢失并且这些情况很有趣。
Basically I need to get the Nieseln area class of available object / Nielsen area of all ( missing and not missing objects ( which is the inq_onr_id==NA
but their object_id
is available)基本上我需要获取可用 object / Nielsen 区域的 Nieseln 区域 class / Nielsen 区域(丢失和未丢失的对象(这是
inq_onr_id==NA
但它们的object_id
可用)
rq_id , rq_object_id , inq_onr_id, inq_id, Nielsen class, age_class, revnue-class , employee_class
157467 19750137 19750137 NA 3 3 4 2
157467 19750137 19750137 NA 3 3 4 2
423008 19750137 NA NA 3 3 4 2
423008 19750137 NA NA 3 3 4 2
157467 19750137 NA NA 3 2 4 2
B1_fourth3month19short<-data.frame(rq_id,
rq_object_id,
inq_onr_id,inq_id,
nielsen_area,Employeeclass)
All info are factors in principle.原则上,所有信息都是因素。
What I want to take out is to find out how the fre(rq_object_id)
vs Nieslen area changes in the case where the onr-id
is missing vs where the onr _id
is available.我想了解的是,在
onr-id
缺失与onr _id
可用的情况下, fre(rq_object_id)
vs Nieslen 区域如何变化。
What you need to use is table
:您需要使用的是
table
:
out <- table(df[,c(2,3,5)],useNA = "ifany")
where df
is your initial data frame.其中
df
是您的初始数据框。
Output: Output:
> out
, , Nielsen_class = 3
inq_onr_id
rq_object_id 19750137 <NA>
19750137 2 3
To get the percent of each row, do the following:要获取每行的百分比,请执行以下操作:
out.percent <- prop.table(table(df[,c(2,3,5)],useNA = "ifany"))*100
Output in percent: Output 百分比:
> out.percent
, , Nielsen_class = 3
inq_onr_id
rq_object_id 19750137 <NA>
19750137 40 60
