我遇到一组数据如下
"age" "car.age" "type" "cost" "number""17-20" "0-3" "A" 289 8"17-20" "4-7" "A" 282 8"17-20" "8-9" "A" 133 4"17-20" "10+" "A" 160 1"17-20" "0-3" "B" 372 10"17-20" "4-7" "B" 249 28"17-20" "8-9" "B" 288 1"17-20" "10+" "B" 11 1"17-20" "0-3" "C" 189 9"17-20" "4-7" "C" 288 13"17-20" "8-9" "C" 179 1"17-20" "10+" "C" 0"17-20" "0-3" "D" 763 3"17-20" "4-7" "D" 850 2"17-20" "8-9" "D" 0"17-20" "10+" "D" 0"21-24" "0-3" "A" 302 18"21-24" "4-7" "A" 194 31"21-24" "8-9" "A" 135 10"21-24" "10+" "A" 166 4"21-24" "0-3" "B" 420 59"21-24" "4-7" "B" 243 96"21-24" "8-9" "B" 196 13"21-24" "10+" "B" 135 3"21-24" "0-3" "C" 268 44"21-24" "4-7" "C" 343 39"21-24" "8-9" "C" 293 7"21-24" "10+" "C" 104 2"21-24" "0-3" "D" 407 24"21-24" "4-7" "D" 320 18"21-24" "8-9" "D" 205 2"21-24" "10+" "D" 0
用R 语言应该使用什么代码分析此类数据，望精通R 语言的高手赐教，指点指点

就是分析数据中的cost 和number 与age、type 以及car.age的联系，由于age、type 和car.age 都是区间变量或者是属性变量，
不知道选用什么办法分析，感觉要用category method to analysis this data, but it is difficult to building an appropriate model for this data.
so I need somebody give me some suggestions.
是有点复杂啊
