Percentage histogram with facet_grid: x variable is a factor - r
I want to split a percentage histogram (that integrates to 100%) into two facets using facet_grid. However, when splitting to facets, each facet by itself doesn't integrate to 100%. This kind of question has been resolved here in the past, but I cannot translate that solution to my current situation where x is a factor, and thus a histogram using stat(density) doesn't work.
My Data
Dataframe with two columns. equipment denotes whether a household has enough equipment for homeschooling, and children_n denotes number of children.

Now I want to plot the proportion of number of children in two separate panels: one panel for families who have enough equipment, and another panel for families who don't have enough equipment:
df %>%
ggplot(data = ., aes(x = children_n, y = equipment)) +
geom_histogram(aes(y = (..count..)/sum(..count..)), stat = "count" , fill = "darkblue") +
geom_text(aes(label = scales::percent(((..count..)/sum(..count..)), accuracy = 1),
y = ((..count..)/sum(..count..)) ), stat= "count", vjust = -.5, color = "darkblue") +
scale_y_continuous(labels = scales::percent) +
facet_grid(~ equipment, labeller = as_labeller(c("1" = "have enough equipment",
"0" = "don't have enough equipment")))
This gives two panels that *DON'T* integrate to 100% independently:
Trying to solve the problem
I found this question that describes the same intention and problem. The chosen solution suggests defining the geom_histogram as density so it integrates to 100%. But this won't work in my case because stat(density) asks that the x variable will be continuous, unlike my case where x is a factor.
df %>%
ggplot(data = ., aes(x = children_n, y = equipment)) +
geom_histogram(aes(y = stat(density) * 6), binwidth = 6, fill = "darkblue") +
facet_grid(~ equipment, labeller = as_labeller(c("1" = "have enough equipment",
"0" = "don't have enough equipment")))
Error: StatBin requires a continuous x variable: the x variable is
discrete. Perhaps you want stat="count"?
Other approaches suggest using ..PANEL.. while others are strongly against it.
How can I get the two facets to show percents that independently integrate to 100%, in a proper way?
This could be achieved like so:
Map the facetting variable on the group aes
Use e.g. tapply to get the total number per group or facet
BTW: I have put the code for the normalization inside a helper function to reduce the code duplication and readability

Output list of variables with significant p-values from several regressions in R
I have a dataframe that looks like the following.
consistent admire trust judge
3 3 2 4
5 1 3 6
2 4 5 1
I can run the regressions I need simultaneously using the following code. In the actual dataset, there are many more than 3 variables.
variables <- c("admire", "trust", "judge")
form <- paste("consistent ~ ",variables,"")
model <- form %>%
set_names(variables) %>%
map(~lm(as.formula(.x), data = df))
map(model, summary)
This yields the output for the 3 following regressions.
summary(lm(consistent ~ admire, df))
summary(lm(consistent ~ trust, df))
summary(lm(consistent ~ judge, df))
I would like a list of the variables with significant p-values at p < 0.05. For example, if "admire" was significant and "judge" was significant, the output I am looking for would be something like:
admire, judge
Is there a way to do this that allows me to also run several regressions simultaneously? This question offers a similar answer, but I don't know how to apply it when I have several regressions.

Bootstrapping multiple regression error: number of items to replace is not a multiple of replacement length
I want to bootstrap my dataset for multiple regression. Unfortunately I get this error message:
"number of items to replace is not a multiple of replacement length"
I suspect that the factors in my regression formula may be problematic.
What could I do to solve my problem?
My code is as following (I read Andy Field´s Discovering Statistics using R):
BootReg <- function(data, indices, formula) {
d <- data[indices,]
fit <- lm(formula, data=d)
return(coef(fit))
}
bootResults <-boot(statistic = BootReg, formula = TICS_Skala1 ~HSPhoch + HSPhoch*extra.c
+ psy + sex + age.c, data = mod.reg.data, R = 2000)
psy (psychiatric disease), sex and HSPhoch (high sensory-processing sensitivity) are factors. TICS_Skala1, extra.c, age.c are continuos variables.
my sample data:

Partial Credit Model: How to calculate the item difficulty?
I have a dataframe with credits of participants for several items. I would like to calculate the item difficulty of those items. With the eRm Package I can calculate the difficulty for the different categories of each item:
Some data:
x1 <- c(1, 2, 1, 0, 3, 3, 0, 4, 4, 1, 0, 3, 2, 0, 4, 1, NA, 1, 1, NA, 0, 1, 2, 1, 1, 3, 0, 2, 1, 0)
x2 <- c(0, 1, 0, 3, 2, 0, 1, 2, 2, NA, 0, 1, 2, 2, NA, 1, 2, 1, 2, 1, 0, 2, 3, 0, 1, 1, 0, 1, 1, 3)
x3 <- c(NA, NA, 3, 0, 1, 2, 0, 1, 1, NA, 3, 0, 1, 2, 0, 1, 2, 1, 0, 1, 3, 1, 3, 0, 1, 1, 0, 1, 1, 0)
x4 <- c(3, 0, 2, 2, 3, 2, 1, 2, 0, 0, 1, 0, 1, 1, 0, 1, 2, 1, 1, 2, 0, 1, 1, 2, 1, 1, 0, 1, 1, 0)
x5 <- c(1, NA, 1, 1, 1, 0, 1, 1, 0, 1, 1, 0, 1, 1, 0, 1, NA, 1, 1, 1, 0, 1, 1, 0, 1, 1, 0, 1, 1, 0)
dat <- data.frame(x1, x2, x3, x4, x5)
library("eRm")
Calculation of category difficulties:
PCM(dat)
PCM(dat)$etapar
I do not need the difficulty for the categories, but for the whole item. How can I calculate the overall difficulty of each item?
Thank you very much in advance!
Imputing missing values keeping a rectangular shape in mind
I have a data set where number denotes a particular color. Since i have large data set, i am sharing a sample data and work. I am looking forward to create this Output d <- matrix(c( 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 1, 1, 2, 3, 3, 2, 1, 1, 2, 3, 3, 2, 1, 1, 2, 3, 3, 2, 1, 1, 2, 3, 3, 2, 1, 1, 2, 2, 2, 2, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1), nrow=13, byrow = TRUE) from this Input : d_mi <- d d_mi[ sample(1:length(d), length(d)*0.3) ] <- NA d_mi Optional : Output(in color mode)
