There's something wrong in my aseg code..

[lsmtgr]

Hello !
This is my R code

brain <- tibble( region = c("thalamus proper", "putamen", "caudate", "pallidum", "hippocampus",
"amygdala"),
p = c("0.00022", "0.0262", "0.000945", "8.6E-04", "6.3E-03", "0.006093"),
)

brainx <- brain %>% filter(p < 0.05)
ggplot(brainx) + geom_brain(atlas = aseg, side = "coronal", hemi = "left", aes(fill = p)) +
scale_fill_viridis_c(option = "cividis", direction = -1) +
theme_void() +
labs(title = "R basal")

"An error message similar to the image above appeared. What might be wrong?"

Hi!

The error message is saying that you are trying to apply a continuous scale to a discrete value.

You've entered the p values with quotes, meaning R thinks they are a categorical scale. Unquote your numbers and everything should be fine.

This is not a ggseg specific thing, but ggplot2.
