Only the map legend appearing in ggplot - r

I am trying to plot data on a map. However, only the legend appears on a blank graph. The data set.

The code that I have tried:
map1<-ggplot(final.plot1, aes( x = long, y = lat, group=id)) +
geom_polygon(aes(fill = low_prestige), color = "black")
map1

Another option is using the sf package which is useful to plot geographic data in combination with ggplot. Here is a reproducible example:
library(ggplot2)
library(sf)
#> Linking to GEOS 3.10.2, GDAL 3.4.2, PROJ 8.2.1; sf_use_s2() is TRUE
your_sf <- st_as_sf(final.plot1, coords = c('long', 'lat'))
ggplot(your_sf) +
geom_sf(aes(color = low_prestige))

Change the column width on a tableGrob using ttheme_minimal

I'm trying to build a table using tableGrob in gridExtra and can't figure out how to set the column with. I am using ttheme_minimal(base_size = 25) to set the size of the text, but I can't seem to find a way in that function to se the column widths. Below is the full code that I'm using:
team_free_agents <- structure(list(Player = c("Adrian Amos", "Dean Lowry", "Marcedes Lewis",

tt1 <- gridExtra::ttheme_minimal(base_size = 25)
fa_table <- gridExtra::tableGrob(team_free_agents,

Any help with this would be appreciated!

And the code I tried :
library(janitor)
autres %>%
adorn_totals("row")
Could anyone help ? I had indeed used the adorn_totals function on the dataframe used to generate the dataframe "autres", but I made sure the row "total" isn't in the dataframe "autres" anymore.
With the object you have shared as x:
x %>%
untabyl() %>%
adorn_totals()
Why it works:
You can see at the end of the object you shared, tabyl_type = "two_way", totals = "row". Those attributes are stored with the data.frame you're working with. When you try to adorn_totals() a second time, janitor checks this and errors.
When you call untabyl() it strips those attributes. Then adorn_totals() succeeds.
I notice you have a cumulative percentage column. If desired, you can control exactly which columns get a totals value in adorn_totals() - see ?adorn_totals and the ... argument for how, and here's an example: https://stackoverflow.com/a/69759313.

xlab("Duration")
How can I get sth that looks like this:
You should first make sure to calculate common xmin-xmax to both series.
Then with patwhwork a suggested in comments or cowplot:
xmin <- min(df$ADY ,df2$AESTDY)
xmax <- max(df$ADY ,df2$AESTDY)
p1 <- ggplot(df, aes(colour=SDTM_LabN)) +
geom_line(aes(x=ADY,y=result)) +

How to summarise (dplyr) user specified variables reactively in flexdashboard/shiny?

I am trying to develop a shiny dashboard app that is able to produce a bar graph for different outcome variables that can be selected by the user. To do so, I need to subset my data reactively to generate aggregate data frames. I am able to have the code below successfully filter my data reactively, but I am running into trouble when I try to use dplyr::summarise() reactively.
Here is my data
dput(head(df))

#List of potential outcome variables to be plotted

# Define inputs
selectInput('state_name', label = 'Select a state', choices = lookup)
selectInput('DV', label = 'Outcome Measure', choices = variables)
#Filter data based on the State and outcome measure the user would like to investigate.
bar <- reactive({
st <- df %>%
filter(state == input$state_name)
bp <- st %>%
group_by(tract_type) %>%
summarise(Outcome = mean(st[,input$DV]))
return(bp)
})
bar
UPDATE
Right now, this code successfully filters the data by the input$state_name, but there is an issue with the calculation of means. The result is this:
# A tibble: 2 x 2
tract_type Outcome
<chr> <dbl>
1 Contiguous 468296.
2 LICs 468296.
As you can see, the means that are calculated are identical. In fact, these values correspond to the grand average mean for whichever variable is chosen for input$DV. Therefore, the filtered st data is not being successfully grouped into the two levels of tract_type.
I see what you are trying to do. The difference is that in your reactive part you try to calculate the mean of a string, which won't work. What you want to do is summarise one of the columns in df by providing the name
In the following example, I specify the summarising variable manually. Note that investment_score_1_low_10_high does not have quotes. investment_score_1_low_10_high is what is called a symbol in R.
st <- df %>%
filter(state == "Alabama") %>%
group_by(tract_type) %>%
summarise(Outcome = mean(investment_score_1_low_10_high))
But I think this should work:
bar <- reactive({
# Create a symbol from string.
mean_variable <- sym(input$DV)
bp <- df %>%
filter(state == input$state_name) %>%
group_by(tract_type) %>%
summarise(Outcome = mean(!! mean_variable, na.rm = TRUE))
return(bp)
})
Extra information about the use of !! and what it does can be found here: Here
And even better with examples Here
Solution derived by #dylanvanw
bar <- reactive({
# Create a symbol from string.
mean_variable <- sym(input$DV)
bp <- df %>%
filter(state == input$state_name) %>%
group_by(tract_type) %>%
summarise(Outcome = mean(!! mean_variable, na.rm = TRUE))
return(bp)
})
