QUESTION
I am wondering if there's a way to bind a dataframe on the left hand side instead of putting them on the right hand side through dplyr()
. This is because when I am working on a long dplyr()
cleaning on the second dataset and the final step is to bind the dataset to the first dataset (main dataset). If I use bind_cols()
, the second dataset is always joined on the right hand side. Is there a way I can force the first dataset to join on the left hand side of the second dataset in a long dplyr script.
- Obviously, I can make one line syntax indepdently and start with the first dataset and use
bind_cols()
to bind it with the second dataset. I am just wondering if there's anyting I can do at the end of a long dplyr script?

I would like to obtain the estimation sample from a model object, i.e. the observations that were not dropped due to missing values. This seems to be simple for standard lm
regressions (using case.names()
) but less so for more recent packages such as fixest
.
Is there any general way to access the estimation sample, irrespective of the package used for estimation?
My attempts for both lm
and fixest
objects are:
ANSWER
Answered 2021-Jun-09 at 14:57Generic function case.names
has no method written for objects of class "fixest"
. The solution is to look at str(mod_fe)
and write your own method.

I have a set of Fisher's discriminant linear functions that I need to multiply against some test data. Both data files are in the form of two matrices (variables lined up to match variable order), so I need to multiply them together.
Here is some example test data, which I've added a constant=1 variable (you'll see why when you we get to the coefficients)

I am a newbie in data analysis. I wish to know how to boxplot multiple columns (x-axis = Points, Score, Weigh) in a single graph and make the y-axis as a standardized scale for comparison. I have tried and couldn't understand the code (Python+Pandas+Seaborn) for this. Help me out guys. The dataset for the same is as follows:
Cars Points Score Weigh 0 Mazda RX4 3.90 2.620 16.46 1 Mazda RX4 Wag 3.90 2.875 17.02 2 Datsun 710 3.85 2.320 18.61 3 Hornet 4 Drive 3.08 3.215 19.44 4 Hornet Sportabout 3.15 3.440 17.02 5 Valiant 2.76 3.460 20.22 6 Duster 360 3.21 3.570 15.84 7 Merc 240D 3.69 3.190 20.00 8 Merc 230 3.92 3.150 22.90 9 Merc 280 3.92 3.440 18.30 10 Merc 280C 3.92 3.440 18.90 11 Merc 450SE 3.07 4.070 17.40 12 Merc 450SL 3.07 3.730 17.60 13 Merc 450SLC 3.07 3.780 18.00 14 Cadillac Fleetwood 2.93 5.250 17.98 15 Lincoln Continental 3.00 5.424 17.82 16 Chrysler Imperial 3.23 5.345 17.42 17 Fiat 128 4.08 2.200 19.47 18 Honda Civic 4.93 1.615 18.52 19 Toyota Corolla 4.22 1.835 19.90 20 Toyota Corona 3.70 2.465 20.01 21 Dodge Challenger 2.76 3.520 16.87 22 AMC Javelin 3.15 3.435 17.30 23 Camaro Z28 3.73 3.840 15.41 24 Pontiac Firebird 3.08 3.845 17.05 25 Fiat X1-9 4.08 1.935 18.90 26 Porsche 914-2 4.43 2.140 16.70 27 Lotus Europa 3.77 1.513 16.90 28 Ford Pantera L 4.22 3.170 14.50 29 Ferrari Dino 3.62 2.770 15.50 30 Maserati Bora 3.54 3.570 14.60 31 Volvo 142E 4.11 2.780 18.60My output should look something like: Output Boxplot Graph

QUESTION
I am trying to subsample a data.frame in a way that the sample would have observations that capture as much variation as possible among a set of columns of the original data.frame.
An example with the mtcars
dataset: I'd like to find 3 cars that are the most different from each other by mpg
, vs
and carb
. Looking at the data visually, it would probably be Toyota Corolla (high mpg
, vs
1, low carb
), Cadillac Fleetwood (low mpg
, vs
0, medium carb
) and either Maserati Bora (low-med mpg
, vs
0, high carb
) or Ferrari Dino (medium mpg
, vs
0, med-high carb
):
ANSWER
Answered 2021-Mar-20 at 15:12I am not exactly sure if this is what you are looking for, but here it goes:
calculate a distance matrix, giving you information about how "far away" each car is from all other cars, based on all the attributes they have (the default for
dist()
is eucledian, which you can change).Then take the rowsums or colsums (same thing) from that matrix, which just sums up for each car what the combined distance to all other cars is.
Then isolate those cars with the biggest distances (here, we want 3 cars)
Finally subset your dataframe to only include those cars:
QUESTION
As part of my answer to this post, I suggested a completely generic mechanism by which one data frame could be filtered by conditions stored in another. The OP has called me out (damn!) and asked me for an implementation.
My solution requires me to store functions in the filter dataframe. This is possible: this post shows how.
As a basic example, consider
