The min.size
argument is there. In this example, I set it to a ridiculous high number and no contour is labelled.
library(metR)
library(ggplot2)
ggplot(temperature[lev == 300], aes(lon, lat, z = air)) +
geom_contour_fill() +
geom_contour(color = "black") +
geom_text_contour(min.size = 500) +
scale_fill_divergent()

Thanks for your response, it solved my problem.
My bad is that I was trying to put contours and labels directly with geom_contour2
(which doesn't have a min.size
parameter), instead of using 2 geoms (geom_contour
and geom_text_contour
).
As of the recent release, you can label contours with geom_contour2(aes(label = ..level..)
, but it doesn't have that functionality, since it depends on the isoband package, which doesn't have that option control over contouring.
Hi Elio, In the "Visualization tools vignette" says that "Since in some datasets there can be very small contours that should not be labelled for clarity, the
min.size
argument specifies the minimum points a contour has to have in order to be labelled". However,min.size
parameter is not available. Has the parameter name/usage changed o is it a feature for a future version? I'm working with metR v.0.11.0 in R.3.6.3Thanks a lot for this package, I look forward to use some other features. Miguel
