When I use ggplot and when I use stat_smooth() I get automatic messages like this:
geom_smooth()using method = 'loess' and formula 'y ~ x
The problem is I use RMarkdown to build a PDF and I want to show some plots there. This message will be shown there like this:
How can I turn this message off? Or any way to not show it on the PDF with the plots.
If you replicate this example in RMarkdown, do you still get the error?
library(tidyverse)
set.seed(123)
df <- data.frame(group = as.factor(rep(1:3, each = 50)),
week = rep(1:50, 3),
rate = c(round(700 - rnorm(50, 100, 10) - 1:50 * 2, 0),
round(1000 - rnorm(50, 200, 10) - 1:50 * 2, 0),
round(1000 - rnorm(50, 200, 10) - 1:50 * 2, 0)))
df %>%
ggplot(aes(x = week,
y = rate,
group = group,
lty = group)) +
geom_line() +
geom_point() +
geom_smooth()
** This prints the warning/info **
Then try changing the final line:
library(tidyverse)
set.seed(123)
df <- data.frame(group = as.factor(rep(1:3, each = 50)),
week = rep(1:50, 3),
rate = c(round(700 - rnorm(50, 100, 10) - 1:50 * 2, 0),
round(1000 - rnorm(50, 200, 10) - 1:50 * 2, 0),
round(1000 - rnorm(50, 200, 10) - 1:50 * 2, 0)))
df %>%
ggplot(aes(x = week,
y = rate,
group = group,
lty = group)) +
geom_line() +
geom_point() +
geom_smooth(formula = y ~ x, method = "loess")
** No warning/info **
If rmarkdown is being used then making use of chunk options can be useful. So in your chunk set it like this:
{r warning=FALSE, message=FALSE}
You can turn off warnings and messages for the whole document by running this code in the first chunk:
```{r include=FALSE}
knitr::opts_chunk$set(warning=FALSE, message=FALSE)
```
This 'message' is not a message as far as R markdown is concerned, nor is it a warning. Check out this link for a resolution to this problem.
