在Anaconda: Jupyter notebook r中出现此错误

Question

当我在r中执行代码时，我得到了下面的错误。

optbin(train)错误:could not find function "optbin"回溯:

下面是我的代码:

#Read datasets
#Download the data from http://www.saedsayad.com/datasets/CreditData.zip
train <- read.csv("Credit_train.csv")
test <- read.csv("Credit_test.csv")
#Rows and Cols
dim(train)
dim(test)
#Columns name
colnames(train)
colnames(test)
#Show  
head(train)
head(test)

#------
# OneR
#------

#remove all records with missing values
train <- na.omit(train)
test <- na.omit(test)
#binning the numerical variable
train.bin <- optbin(train)
#train
model.OneR <- OneR(DEFAULT~., data = train.bin, verbose = TRUE)
summary(model.OneR)
plot(model.OneR)
#test
pc <-NULL
pc <- predict(model.OneR, test, type = "class")
eval_model(pc,test)

我已经应用了oneR包，它仍然不工作。我必须做什么才能解决这个错误?

Answer 1

在使用函数

之前尝试使用library或require加载库

library(OneR)

或者您可以使用名称空间说明符

OneR::optbin
