I am new to R studio

[thirsty]

Hi Guys,
I am very new to data science, and even more new to R studio, unfrotunateley i am not being able to run my first script.
The downloaded binary packages are in
/var/folders/d4/n9lccmwn1w3dkk42c1ljqbh80000gn/T//RtmprAdHiG/downloaded_packages

murders %>%

• ggplot(aes(population, total, label = abb, color = region)) +
• geom_point()
  Error in murders %>% ggplot(aes(population, total, label = abb, color = region)) :
  could not find function "%>%"

murders %>%

• ggplot(aes(population, total, label = abb, color = region)) +
• geom_point() +
• geom_text(check_overlap = TRUE)
  Error in murders %>% ggplot(aes(population, total, label = abb, color = region)) :
  could not find function "%>%"
  these are the errors i am getting, I am running a CATALINA OS 10.15.4
  I have installed the latest R studio in the beginning, but i uninstalled it , to re-install an earlier version and i am still facing the same issues , i need some help here.
  thanks

looks like you have not loaded the package where the %>% “pipe” operator comes from. The operator comes from magrittr. However I would recommend to load all the basic tidyverse packages with library(tidyverse)

On https://r4ds.had.co.nz/pipes.html you can find a short introduction how the %>% “pipe” operator works. If you are new to R, "R for Data Science" is a good start: https://r4ds.had.co.nz/

Hi Joel,
Thanks a lot, i have installed and loaded tidyverse packages, i have tried to res-install and re-load the packages endless times.

To get to the bottom of the problem:

• First make sure that you are working in a new R Session: ctrl + shift + F10 (in windows) or .rs.restartR() in the command line.
• Second if you load library(tidyverse), what output do you get in the console window?
  Does it look somehow like this?

library(tidyverse)
#> -- Attaching packages -------------------------------------------------------------------------------- tidyverse 1.3.0 --
#> v ggplot2 3.3.0     v purrr   0.3.3
#> v tibble  2.1.3     v dplyr   0.8.5
#> v tidyr   1.0.2     v stringr 1.4.0
#> v readr   1.3.1     v forcats 0.5.0
#> -- Conflicts ----------------------------------------------------------------------------------- tidyverse_conflicts() --
#> x dplyr::filter() masks stats::filter()
#> x dplyr::lag()    masks stats::lag()

^{Created on 2020-04-13 by the reprex package (v0.3.0)}

that's what i get in the console window

Good.

And this is working as well?

library(tidyverse)
mpg %>% select(manufacturer)
#> # A tibble: 234 x 1
#>    manufacturer
#>    <chr>       
#>  1 audi        
#>  2 audi        
#>  3 audi        
#>  4 audi        
#>  5 audi        
#>  6 audi        
#>  7 audi        
#>  8 audi        
#>  9 audi        
#> 10 audi        
#> # ... with 224 more rows

If this is works as well. Could you post a reprex?

A reprex is the preferred way to show folks exactly what you're trying to do, and it'll reproduce any output or error messages you encounter along the way as well, FAQ: What's a reproducible example (`reprex`) and how do I do one?. (copied this sentence from a message by EconomiCurtis in another thread)

[thirsty]

I tried to Load the reprex package and i got an error as well
library(reprex)

library(reprex)
Error: package or namespace load failed for ‘reprex’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
there is no package called ‘fs’
that's why i was not able to produce a reprex to post it here

[joel.gautschi]

Looks like the packages are not installed in a proper way. I do not know a lot about problems with that. One package that seems to be missing is fs but maybe there are more.

You could try first:
install.packages("reprex")
and I guess dependecies (like fs) should be installed. If you want to make sure that fs is installed:
install.packages("fs")
to install these packages.

However, as I said, maybe there are further problems with the installation, and you would need help from somebody else on community.rstudio.com.
