With the following code in R, I got a warning.
res <- fieldByYear(M,
field = "ID", # Metadata field (e.g., Keywords Plus)
timespan = c(2010, 2023),
min.freq = 5, # Minimum total occurrences
n.items = 10, # Number of items to show per year
graph = TRUE)
## Warning: Using `size` aesthetic for lines was deprecated in ggplot2 3.4.0.
## ℹ Please use `linewidth` instead.
## ℹ The deprecated feature was likely used in the bibliometrix package.
## Please report the issue at <https://github.com/massimoaria/bibliometrix/issues>.
