! could not find function %>%

[nathasyaeca]

Hi guys, so I get this issues that puzzle me.

I tried to write run code chunk in RMarkdown using ggplot2, dplyr, and ggrepel packages. Before I move my code in RMarkdown I put it in R Script, and it run smoothly. But when I tried to run it in RMarkdown they send me this message "! could not find function %>%". The code is like this:

total_industry_and_registered %>%
ggplot(aes(x=provinsi, y=jumlah_pendaftar, color=pulau, label=provinsi))+
geom_point()+
labs(title="Number of Registered Industry of Traditional Medicine by Province",
caption = "Source data: Portal Satu Data BPOM",
x="",
y="Total Industry")+
theme(axis.text.x=element_blank(),
axis.ticks.x=element_blank())+
geom_text_repel(size=3)+
theme(legend.position="bottom")

Did anyone has run the same issue as me?

You need to attach the package that has %>%, i.e. write

library(dplyr)

at the beginning of the first chunk that uses it. Or the very first chunk or the document.

Strictly speaking %>% is a part of magrittr, which is called by dplyr. Alternatively, if you are using R version 4.1, or more recent, you can replace this with the pipe symbol |> and it does not require any extra packages.

%>% and |> are mostly interchangeable but behave differently within the tidy dialect than they do in base. The difference lies in how the LHE (left hand expression) is carried over.

library(dplyr)
#> 
#> Attaching package: 'dplyr'
#> The following objects are masked from 'package:stats':
#> 
#>     filter, lag
#> The following objects are masked from 'package:base':
#> 
#>     intersect, setdiff, setequal, union
library(magrittr)
mtcars |> log(mpg)
#> Error in eval(expr, envir, enclos): object 'mpg' not found
