I realize that this is a slightly more complicated application, but in reality, this is a very common way to use case_when in R. We commonly use case_when to create new variables in a dataframe, in conjunction with the mutate function. EXAMPLE 4: Create new variable by multiple conditions...
# select_if() if you want to apply the function to columns of a certain characteristic (e.g. data type) # select_with() if you want to apply the function to columns and include another function within it # 创建新列 # mutate函数 marine5 <- marine4 %>% mutate(genus_species = paste...
work for arbitrary R function, as we don't know if that functions accept vector or a list. In first case all values has to be coerced to same type and copied into new vector. In latter case it could be eventually referenced. But how we can know if function expects a list or vector...
