在R中分配一个数字二进制类的列表(Assigning a list of numbers binary class in R)

 我正在尝试根据以下参数将数字列表转换为二进制类： 
 
 如果该值大于3那么0 
 
 如果该值为3或小于3那么1 
 
 目前我已将下面的if else命令放在一起。 但这是一个错误。 
 
if (df$DaysOverdue[df$daysoverdue == ">3"]) {
df$DaysOverdue[df$DaysOverdue] <- 0 
}
else {
df$DaysOverdue[df$DaysOverdue] <- 1 
}

I'm attempting to transform a list of numbers a binary class based on the below parameters:
 
IF the value is greater than 3 THEN 0
 
IF the value is 3 or less than 3 THEN 1
 
Currently I've put together the below if else command. But this is coming back as an error.
 
if (df$DaysOverdue[df$daysoverdue == ">3"]) {
df$DaysOverdue[df$DaysOverdue] <- 0 
}
else {
df$DaysOverdue[df$DaysOverdue] <- 1 
}
