R初学者:参数不是数字或逻辑:返回NA [英] R Beginner: argument is not numeric or logical: returning NA
问题描述
.csv
文件,有两列,一个是不完整的。由于某些原因,每当我尝试对数据执行基本的统计操作时,我会收到以下消息: 在mean.default(results)中:参数不是数字或逻辑:返回NA
结果是我的集合。关于解决这个问题的任何建议?
从R 3.0.0起意思是(< data 。)
数据框是具有唯一行名称的相同行数的变量列表,给定类data.frame。
在你的情况下,结果有两个变量(如果你的描述是正确的)。您可以使用以下任何一种方式获得列的方法:
lapply(results,mean,na.rm = TRUE)
sapply(results,mean,na.rm = TRUE)
colMeans(results,na.rm = TRUE)
I am an R beginner and having a hard time doing anything in it. I have a data set that originated from an excel file but is now a .csv
file with two columns, one being incomplete. For some reason, whenever I try to run basic stat operation on the data, I get this message:
In mean.default(results) : argument is not numeric or logical: returning NA
Results being my set. Any advice on getting around this problem?
From R 3.0.0 onwards mean(<data.frame>)
is defunct (and passing a data.frame to mean
will give the error you state)
A data frame is a list of variables of the same number of rows with unique row names, given class "data.frame".
In your case, result has two variables (if your description is correct) . You could obtain the column means by using any of the following
lapply(results, mean, na.rm = TRUE)
sapply(results, mean, na.rm = TRUE)
colMeans(results, na.rm = TRUE)
