我正在使用一些基本的R函数,并试图创建一个包含数字1:20的余数和商数的表 首先,我创建了此函数:
Find_Remains = function(number, divisor){
Remainder = number%%divisor
Quotient = number%/%divisor
a = c(number, divisor, Remainder, Quotient)
return(a)
}
我添加一个空白表
final.data.frame = data.frame(matrix(NA, nrow = 1, ncol = 4))
然后我创建了这个for循环
for(i in c(1:20)){
b[i] = Find_Remains(i,5)
final.data.frame = rbind(b[i])
}
我得到的错误是:
number of items to replace is not a multiple of replacement length
任何帮助将不胜感激。谢谢
答案 0 :(得分:0)
初始化final.data.frame
的荣誉(尽管我认为最好用20行初始化)。完成不需要使用rbind
的操作后,您可以在每次循环运行中简单地替换数据帧的每一行。这就是您需要的-
Find_Remains = function(number, divisor) {
Remainder = number%%divisor
Quotient = number%/%divisor
a = c(number, divisor, Remainder, Quotient)
return(a)
}
final.data.frame = data.frame(matrix(NA, nrow = 20, ncol = 4))
for(i in 1:20) {
final.data.frame[i, ] = Find_Remains(i,5)
}
> final.data.frame
