R语言数据框data.frame行和列求和方法
代码如下：widgets <- c(179,153,183,153,154)gadgets <- c(167,193,190,161,181)thingys <- c(182,166,170,171,186)daily.prod <- data.frame(widgets,gadgets,thingys,row.names = c(‘Mon’,‘Tue’,‘Wed’,‘Th
·
代码如下：
widgets <- c(179,153,183,153,154)
gadgets <- c(167,193,190,161,181)
thingys <- c(182,166,170,171,186)
daily.prod <- data.frame(widgets,gadgets,thingys,row.names = c('Mon','Tue','Wed','Thu','Fri'))
rbind(daily.prod,Total=colSums(daily.prod))
cbind(daily.prod,Totol=rowSums(daily.prod))
运行结果
- 列求和
| Date | widgets | gadgets | thingys |
|---|---|---|---|
| Mon | 179 | 167 | 182 |
| Tue | 153 | 193 | 166 |
| Wed | 183 | 190 | 170 |
| Thu | 153 | 161 | 171 |
| Fri | 154 | 181 | 186 |
| Total | 822 | 892 | 875 |
- 行求和
| Date | widgets | gadgets | thingys | Totol |
|---|---|---|---|---|
| Mon | 179 | 167 | 182 | 528 |
| Tue | 153 | 193 | 166 | 512 |
| Wed | 183 | 190 | 170 | 543 |
