Hi, I'm new in R and thanks for welcoming me to this community.
I'm studying the stm topic modeling with R and read this paper What Students Learn in Economics 101: Time for a Change - UCL Discovery
I want to know how could I plot the graph like page 14 if I use stm?

Here is a start on doing that with a generic data frame.
library(ggplot2)
library(dplyr)
#>
#> Attaching package: 'dplyr'
#> The following objects are masked from 'package:stats':
#>
#> filter, lag
#> The following objects are masked from 'package:base':
#>
#> intersect, setdiff, setequal, union
DF <- data.frame(Topic = rep(LETTERS[1:3], each = 4),
Author = rep(c("", "Bob", "", "Amy"), 3),
Value = c(43, 22, -25, -18,
26, 15, -33, -27,
55, 37, -17, -10))
DF1 <- DF %>% filter(Author == "")
DF2 <- DF %>% filter(Author != "")
ggplot(mapping = aes(Topic, Value)) +
geom_col(data = DF1, color = "black", fill = "white") +
geom_col(mapping = aes(fill = Author), data = DF2) +
scale_fill_manual(values = c("Amy" = "grey80", "Bob" = "grey50") ) +
ylim (-60, 60) +
coord_flip() + theme_minimal() +
theme(panel.grid.major.x = element_blank(),
panel.grid.minor = element_blank())
