Trying to change theme elements for plot.tag but only applying to one tag_level letter

[daniellembecker]

Hi I am trying to change the size and face of the tag_levels on my plots but whenever I run the code below for two plots:

prod_combined_plot <- (production_plot | kelp.treatment) +
plot_annotation(tag_levels = 'A') +
theme(plot.tag = element_text(face = "bold", size = 18));prod_combined_plot

Only the second letter (B) changes size and becomes bold while A stays the same. Both plots are made the same way and have the same dimensions.

In patchwork, when adding new ggplot2 elements (e.g. theme()) the + operator mean "add to the last plot". If you want to make a change that affects all the plots in the patchwork you should use the & operator instead. See https://patchwork.data-imaginist.com/articles/guides/assembly.html#modifying-patches

Hi, I tried this

fig = (p1+p2)/(p3+p4)
fig & theme(plot.tag = element_text(size = 10))

but got error

Error in fig & theme(plot.tag = element_text(size = 10)) : 
  operations are possible only for numeric, logical or complex types
In addition: Warning message:
Incompatible methods ("Ops.S7_object", "&.gg") for "&"
