我正在尝试构建一个 devtools 包，并且我需要在我的代码中使用此循环：

for (i in 1:length(idk)){
  tritemp=intetemp[intetemp$path %in% idk[i],]
  tritemp=tritemp %>%
    group_by(grp = paste(pmax(from, to), pmin(from, to), sep = "_")) %>%
    slice(1) %>%
    ungroup() %>%
    select(-grp)
  interac=rbind(interac,tritemp)
}

不幸的是，当我运行 devtools 检查时，出现以下错误：

interactions: no visible global function definition for '%>%'
  interactions: no visible binding for global variable 'from'
  interactions: no visible binding for global variable 'to'
  interactions: no visible global function definition for 'slice'
  interactions: no visible global function definition for 'ungroup'
  interactions: no visible global function definition for 'select' …
