Function not returning dataframe, pipe inside of function

General

1

I want to create a function with which I can look for a country and then get the corresponding data.

I want to use the function in shiny to create an interactive graph. User looks for country and gets corresponding visualisation.

The data:

dput(Global[1:300, ])
structure(list(country = c("Afghanistan", "Afghanistan", "Afghanistan", 
"Afghanistan", "Afghanistan", "Afghanistan", "Afghanistan", "Afghanistan",

The code:

GlobalLifeExp <- function(land) {
                    z <- Global %>% 
                             group_by(country) %>%
                             filter(country == "land") 
                
                   return(z)
                         
                 }

GlobalLifeExp(Albania) == > is not working, I get this message:

# A tibble: 0 x 3
# Groups:   country [0]
# … with 3 variables: country <chr>, Year <chr>, Life_Expectancy <dbl>

I get the same result with:

GlobalLifeExp <- function(land) {
     
          a <- group_by(Global, country)
          b <- filter(a, country == "land") 
     
     return(b)
     
 }

May I ask why this is not working? Thank you.

Could you try replacing "land" by land, and see if that helps? The first is a string object, the second is the name of the object the function is being applied to.

3

Your filter statement is looking for the cases where the country variable equals the character string "land", not the variable land. Try:

GlobalLifeExp <- function(land) {
     
          a <- group_by(Global, country)
          b <- filter(a, country == land) 
     
     return(b)
     
 }

No it did not help. Outside of the function the pipe works.

Sorry, but your suggestion is not working.

That surprises me. The following code generates what I believe you're anticipating.

Sorry, I did not use "...", you were correct. It worked. Sorry about this.

Is there a way to have the input without using ".."? I want to use the function in shiny.

User enters country and data is visualised.

Actually it works fine in shiny, without having to use "..". Thank you for your help.
