为什么 rowSums 对某些变量起作用而对其他变量不起作用？

Question

我正在使用以下代码行从其他变量创建新变量：

FER_TMS_nopractice_recoded_replaced %>% select(FACE.RT, SCRAM1.RT_total, SCRAM2.RT_total, SCRAM3.RT_total, 
                             SCRAM4.RT_total, SCRAM5.RT_total, SCRAM6.RT_total, SCRAM7.RT_total, SCRAM8.RT_total, 
                             SCRAM9.RT_total, SCRAM10.RT_total, SCRAM11.RT_total, SCRAM12.RT_total, RESPOND.RT_total, 
                             WHITE4.RT_total) %>% rowSums(na.rm = TRUE) -> FER_TMS_nopractice_recoded_replaced$RT_TOTAL

问题是，虽然它对某些列工作正常，但对于其他列，我收到以下错误： FACE.RESP + RESPOND.RESP 错误：二元运算符的非数字参数

所有 columns/variables 都包含 NA 值，我不明白为什么代码针对某些变量而不是其他变量执行。有任何修复建议吗？

数据结构：

    NA_integer_), SCRAM12.RT = c(NA_integer_, NA_integer_, NA_integer_
    ), RESPOND.RT = c(251L, 1111L, 426L), WHITE4.RT = c(NA_integer_, 
    NA_integer_, NA_integer_)), row.names = c(NA, 3L), class = "data.frame")

Answer 1

根据 dput 输出，其中两列不是 numeric，即 FACE.RT 和 RESPOND.RESP。我们可以使用 mutate_at 将它们转换为 numeric，现在代码可以工作了

FER_TMS_nopractice_recoded_replaced <- FER_TMS_nopractice_recoded_replaced  %>% 
                          mutate_at(vars(FACE.RT, RESPOND.RESP), as.numeric)

为什么 rowSums 对某些变量起作用而对其他变量不起作用？

Why does rowSums work for some variables and doesn't vork for others?

r
