QUESTION
I did linear regression analysis between the response variable(y) and predictor variables in the surgical data set considering pindex as a confounding variable. I aim to plot the response variable(y) against the experimentally determined values of the predictor variables and to this end, I am Successful. However, could not able to indicate the estimated regression and p-value in the ggplot2. In the code below, trying to do the analysis and the plot. It would be much appreciated if someone could show me how to indicate the estimated regression and p-values inside the ggplot2.
...ANSWER
Answered 2021-Jun-04 at 10:33You can add the equation and p-value to the plot using the "stat_poly_eq" function from the ggpmisc package:

I have some results from a perm.t.test
that I would like to transform into a data frame. I've tried a lot and searched a lot but I don't manage to fix this, I'm still new to R.
This is a reduced version of my dataset:

tidy_result <- function(result) {
tibble(
estimate = result$estimate,
statistic = result$statistic,
conf.low = result$conf.int[1],
conf.high = result$conf.int[2],
perm.p.value = result$perm.p.value
)
}
combn(levels(data$t), 2, function(x) {
perm.t.test(exparat~t,data = subset(data, t %in% x), R=999, paired = T)
}, simplify = FALSE) -> result

QUESTION
I have a dataframe that I want to run linear models on by group, then use the broom package to extract the slope and r squared for each model. So far I am trying this:
...ANSWER
Answered 2021-May-29 at 18:02I think simply adding ungroup()
achieves what you need:
QUESTION
I am reading a json
file as a response from api
which is nested and when I look at them in a dataframe/table structure format then there are data frame under data frame.
I have saved file at github location.
...ANSWER
Answered 2021-May-26 at 07:50You can unnest
the sessions
variable and the slots
variable within it to get a long dataframe.
QUESTION
I'm running a list of ordered logit models with different variables etc. I want to convert the output into a tidy tibble to use in ggplot etc. (I also want to save the 'regular model output' so I want to do this separately.)
I want to do this in an automated way, using purrr or lapply or some such, to be able to first 'run all the models' (automating that is another question for later) and then 'tidy all the models', the latter presumably generating a list of tibbles.
I've tried the following, but it throws: Error: No tidy method recognized for this list.
ANSWER
Answered 2021-May-19 at 03:22Something like this ?

How can I convert the summary run on a data.frame into a data.frame itself? I need a data.frame as an output to knitr::kable in RMarkdown.
In particular I have this dataframe

Answered 2021-May-23 at 00:20We could use the matrix

QUESTION
I found a nice function on OSF, which I would like to apply to my own data: https://osf.io/huy8b/
However, if I try to use the lapply function, I get an error. My code and sample data (my own dataset is much bigger) are here.
...ANSWER
Answered 2021-Mar-29 at 13:49These are not suitable places to use lapply
. The functions just take the data frames as inputs, so you can just use the functions. For example:
QUESTION
I have a large df that follows the structure below. For each of 200 groups, I want to fit a linear model to 30 years of data, then extract the slope and the R squared.
...ANSWER
Answered 2021-May-16 at 20:22Just putting i
after a variable name won't automatically create a new object. I think what you want to do is make a list with 200 indices containing the individual data frames that you want.
QUESTION
I am trying to perform a linear regression fit using tidymodels
,parsnip
but encounters the following error:
ANSWER
Answered 2021-May-14 at 14:26The main issue is that you need to assign the fitted model to an object; in your case it would also be fit
.
There are two other points to consider:
- it's confusing/not best practice to assign variables with the same name as R functions (i.e. you might want to call your fit
fit0
ormy_fit
or something rather thanfit
); usually you can get away with it but it breaks, confusingly, in some contexts broom.mixed
is a red herring. Thebroom
package is actually used forlm
fits (and you don't need to load it, apparentlytidymodels
loads it (andparsnip
) automatically ...)
QUESTION
When in view mode, I try to fill in and get the date, it always turns out to be empty, but for example, the string field is filled in. And if I don't use the ViewModel, but only the Booking model, the date is filled in. I would like the date to be filled in with the viewmodel as well...
Controller:
...ANSWER
Answered 2021-May-03 at 13:39The problem is, you're posting CheckInDate
and CheckOutDate
in the html form, while it should be booking.CheckInDate
and booking.CheckOutDate
. Remove the name in your view, so name
will be set with the value provided in asp-for
.
