Add Chi test to plot_stackfrq in R - r

I need to add to the plot_stackfrq in R the Chi test, I didn't see any parameter of the function that accepts chi.test or similar.
This is my code:
library(tidyr)
library(data.table)
homes2 <- homes %>% mutate(rn = rowid(Educ_level)) %>%
pivot_wider(names_from = Educ_level, values_from = Insurance)
plot_stackfrq(homes2[,c("High Scholl","College","Elementary")],
geom.colors = c("YlOrBr"))

I could resolve it with plot_xtab, this did show me Chi test as I needed.
plot_xtab(homes2$Educ_label, homes2$Insurance, bar.pos = "stack", show.total = FALSE, margin = "row", coord.flip = TRUE, show.n = FALSE, show.summary = TRUE,
geom.colors = c("YlOrBr"))

how to move chart to the left with echart4r

this is my chart and it has a blank space on the left, and I want to move the chart so the blank space is reduced
df_x %>%
e_chart(Description) %>%
e_bar(max, label =list(show= T , position = "right", formatter = "{b}")) %>%
e_tooltip(trigger = "axis") %>%
e_flip_coords() %>%
e_y_axis(axisLabel = list(inside = TRUE),
axisTick = list(show = FALSE),
axisLine = list(show = FALSE)) %>%
e_legend(show = FALSE)
here is my code
You can use the e_grid() function to adjust the padding.
For example e_grid(left = '5%')

Set significant digits in summary_rows() using gt package

I'm trying to set number of significant digits inside the summary_rows() function to format mean and sd outputs as following:
library(gt)
library(tidyverse)
iris %>%
gt(groupname_col = "Species") %>%
summary_rows(
groups = TRUE,
columns = c(Sepal.Length:Petal.Width),
fns = list(
Mean = "mean",
SD = "sd"),
formatter = fmt_number(n_sigfig = 1))
But returns that argument "data" is missing.
Any idea?
Thanks!
according to the documentation are the '...' for additional parameters of the formatter:
library(gt)
library(tidyverse)
iris %>%
gt(groupname_col = "Species") %>%
summary_rows(
groups = TRUE,
columns = c(Sepal.Length:Petal.Width),
fns = list(
Mean = "mean",
SD = "sd"),
formatter = fmt_number, n_sigfig = 1)

Display Alternative color_bar value in Formattable Table

Is it possible to populate a formattable color_bar with an alternative display value (i.e. a value other than the value used to determine the size of the color_bar)
In the table below I want to override the values with the following display values for ttl to:
c(1000,1230,1239,1222,1300,1323,1221)
library(tidyverse)
library(knitr)
library(kableExtra)
library(formattable)
tchart <- data.frame(id = 1:7,
Student = c("Billy", "Jane", "Lawrence", "Thomas", "Clyde", "Elizabeth", "Billy Jean"),
grade3 = c(55,70,75,64,62,55,76),
ttl = c(105,120,125,114,112,105,126),
avg =c(52.31,53.0,54.2,51.9,52.0,52.7,53.0))
tchart %>%
mutate(id = cell_spec(id, "html", background = "red", color = "white", align = "center")) %>%
mutate(grade3 = color_bar("lightgreen")(grade3)) %>%
mutate(ttl = color_bar("lightgray")(ttl)) %>%
mutate(avg = color_tile("white","red")(avg)) %>%
kable("html", escape = F) %>%
kable_styling("hover", full_width = F) %>%
column_spec(4, width = "4cm")
I checked the documentation and didn't see this as a possibility, but I was hoping there was a workaround or custom function solution.
I don't think you can quite pass it another set of values, but there are a couple of options that you might find workable.
One thing to note first is that color_bar() can accept two values - a color, and a function that will take the vector of values and transform them to numbers between 0 and 1. By default, that function is formattable::proportion(), which compares everything against the max value. But if you used your display values for ttl, you could conceivably transform the bars to be whatever length you wanted by writing your own function. (See: https://rdrr.io/cran/formattable/man/color_bar.html)
Another possibility would be to make your own formatter. Some examples here:
https://www.littlemissdata.com/blog/prettytables
So, I think you can put the numbers you want in the display, and hopefully can use a function to transform or map those values to get the bar lengths between 0 and 1 that you're looking for.
Add a new variable ttl_bar to determine the size of the bar, and let variable ttl display the value. I use gsub() to replace the ttl_bar to ttl.
tchart <- data.frame(id = 1:7,
Student = c("Billy", "Jane", "Lawrence", "Thomas", "Clyde", "Elizabeth", "Billy Jean"),
grade3 = c(55,70,75,64,62,55,76),
ttl = c(1000,1230,1239,1222,1300,1323,1221),
avg =c(52.31,53.0,54.2,51.9,52.0,52.7,53.0),
ttl_bar = c(105,120,125,114,112,105,126))
tchart %>%
mutate(id = cell_spec(id, "html", background = "red", color = "white", align = "center")) %>%
mutate(grade3 = color_bar("lightgreen")(grade3)) %>%
mutate(avg = color_tile("white","red")(avg)) %>%
mutate(ttl = pmap(list(ttl_bar, ttl, color_bar("lightgray")(ttl_bar)), gsub)) %>%
select(-ttl_bar) %>%
kable("html", escape = F) %>%
kable_styling("hover", full_width = F) %>%
column_spec(4, width = "4cm")
In a more careful way, rewrite gsub() as this mutate(ttl = pmap(list(ttl_bar, ttl, color_bar("lightgray")(ttl_bar)), ~ gsub(paste0(">", ..1, "<"), paste0(">", ..2, "<"), ..3))).
I come up with a better way to use function in color_bar() as the following code.
override = function(x, y) y / 200
tchart <- data.frame(id = 1:7,
Student = c("Billy", "Jane", "Lawrence", "Thomas", "Clyde", "Elizabeth", "Billy Jean"),
grade3 = c(55,70,75,64,62,55,76),
ttl = c(105,120,125,114,112,105,126),
avg =c(52.31,53.0,54.2,51.9,52.0,52.7,53.0),
ttl_bar = c(1000,1230,1239,1222,1300,1323,1221))
tchart %>%
mutate(id = cell_spec(id, "html", background = "red", color = "white", align = "center")) %>%
mutate(grade3 = color_bar("lightgreen")(grade3)) %>%
mutate(avg = color_tile("white","red")(avg)) %>%
mutate(ttl = color_bar("lightgray", fun = override, ttl)(ttl_bar)) %>%
select(-ttl_bar) %>%
kable("html", escape = F) %>%
kable_styling("hover", full_width = F) %>%
column_spec(4, width = "4cm")

Setting Order of R Highcharter Categories

I noticed that my bar graphs change in order based on alphabetical order. I'm using a selectinput, thus if a person who is selected with a name beginning in A, they are at the top, but if it is a letter after C, then they move to the bottom. This is not based on the value of the bars, but seems tied to the names. How can I keep the ProviderName at top always?
My hc code is below
hchart(
comparison_prov_df,
type = "bar",
hcaes(x = Metric, y = Value, group = ProviderName),
colorByPoint = F,
showInLegend = T,
dataLabels = list(enabled = T)
) %>%
hc_chart(zoomType = "xy") %>%
hc_tooltip(crosshairs = TRUE, shared = FALSE, borderWidth = 1) %>%
hc_credits(
enabled = TRUE,
text = ""
) %>%
hc_add_theme(hc_theme_elementary()) %>%
hc_legend(enabled = TRUE) %>%
hc_exporting(
enabled = TRUE,
filename = "data"
) %>%
hc_title(
text = "Title",
align = "left"
) %>%
hc_yAxis(
title = list(text = "Y Axis"),
labels = list(
reserveSpace = TRUE,
overflow = "justify"
)
) %>%
hc_xAxis(title = "") %>%
hc_tooltip(pointFormat = "{point.y:.1f}")
I am not sure what the original data is like, but I'll provide a simple example of one way to change the order of items on an axis. You can change the order by simply using hc_xAxis and then listing the category order.
library(highcharter)
library(tidyverse)
df %>%
hchart("bar", hcaes(x = category, y = value, group = group)) %>%
hc_xAxis(
categories = list(
"Pineapples",
"Strawberries",
"Apples",
"Plums",
"Blueberries",
"Oranges"
)
)
Output
Data
set.seed(326)
df <-
data.frame(category = rep(c(
"Apples", "Oranges", "Plums", "Pineapples", "Strawberries", "Blueberries"
), each = 2),
value = round(runif(12, min = 0, max = 100)),
group = rep(c(2020, 2021), 6))

Displaying datatable in highcharter tooltip

Using the first block of code in this post I want to create a tooltip that would display the list of doctors visiting a clinic on a particular day.I tried the following code which displays nothing
library(DT)
tltp = DT:: datatable(data.frame(Doctors = x[x$Clinic=="{point.series}"&x$VisitDate == "{point.x}",2]))
hc%>%hc_tooltip(pointFormat = tltp)
I also tried using the tooltip_table which gives error
tltp = tooltip_table(x = NULL, y = x[x$Clinic=="{point.series}"&x$VisitDate == "{point.x}",2]
hc%>%hc_tooltip(pointFormat = tltp)
Error: unexpected symbol in:
"tltp = tooltip_table(x = NULL, y = x[x$Clinic=="{point.series}"&x$VisitDate == "{point.x}",2]
tltp"
Apologies I am not fluent in writing javascript.
As the official page recommend, to use highcharter is good alternative read how highchartsjs works. So, see this example with a simple custom tooltip.
hc <- hchart(visits, "column", x = as.Date(VisitDate), y = freq, group = Clinic) %>%
hc_plotOptions(column = list(
dataLabels = list(enabled = FALSE),
stacking = "normal",
enableMouseTracking = TRUE)
)
Adding the simple tooltip using the column names: Clinic and freq
hc %>%
hc_tooltip(pointFormat = "this is and clinic {point.Clinic} and freq {point.freq}")
The tooltip_table function is to make tables in the tooltip:
tt <- tooltip_table(c("Clinic", "Freq"), c("{point.series.name}", "{point.y}"))
hc %>%
hc_tooltip(pointFormat = tt, useHTML = TRUE)
If you need other data to show in the tooltip you can create the columun:
visits$doctors <- sample(letters, size = nrow(visits))
And then create the chart again (using the new data) and use this column in the tooltip:
hchart(visits, "column", x = as.Date(VisitDate), y = freq, group = Clinic) %>%
hc_plotOptions(column = list(
dataLabels = list(enabled = FALSE),
stacking = "normal",
enableMouseTracking = TRUE)
) %>%
hc_tooltip(pointFormat = "Here is the doctor {point.doctors}")
