例如,假设下面的函数中有rename(as_tibble(iris),petal = Petal.Width)` rr <- function(toRename, newName, dt) { rename_(dt, .dots = rlang::expr(list(!! newName = toRename))) } 在其中,我可以传递一个数据集来重命名,以及将重命名为字符串的元素,我可以调用这些元素: rr('petal'...

The issue would be that plyr also include the same rename function, so if the package was also loaded, it could mask the dplyr::renameraw_data %>% plyr::rename(genotype = Characteristics..genotype.) Error in plyr::rename(., genotype = Characteristics..genotype.) : unused argument (genotyp...
Functions in R主要分三个部分来讲解函数:编写函数所需的基础知识相关语法作用域R语言作用域的规则编写函数所需的基础知识R语言通过function()指令来命名和创建函数。首先要给函数赋值,也就是命名,然后在小括号中写入参数,最后再大括号中写入函数要执行的语句,其基本语法是:f <- func 赋值 数据 泛型 转载 mob...
找不到carat_new，因为您没有更新diamonds。一个选项是更新diamonds：
I tried the dpyr package with the rename_with function but with no success.I tried something like thatrename_with( ~paste0(., "_"), starts_with("War") ) %>% mutate(across( starts_with("War"), ~factor(., 2025:2010) Is there any way to do that in R? I can do it manually ...
It would be desirable that dplyr could have a function for it. I have just discovered this: df1 <- df1 %>% `names<-`(tolower(names(.))) ( from here https://github.com/romainfrancois/budflights/blob/master/gen/gen.R ) But wouldn't it be better to have an specific function with...
