数据类型转换数字到字符串/字符

Question

如何将数字类x = 5更改为字符类

Answer 1

要将数字转换为字符串，可以使用toString()函数。但是您说toString()函数不起作用，请确保您正确使用该函数。下面是演示"numeric"转换的代码片段。";string"

x=5
print(class(x)) # output is "numeric"
new_x = toString(x)  # Converting x to a string here
print(class(new_x))  # output is "character"
print(new_x)  #output is "55"
print(x)  #output is 55

Answer 2

使用as.character()函数将变量的类从数字改为字符

#assign x to 5 (numeric)
x <- 5 
# check class of x (=numeric)
class(x)
# output: [1] "numeric"
# change x class to character
x <- as.character(x)
# check x class (= character)
class(x)
# output: [1] "character"
