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 18.60

I have created a reactive function in the server to get a list of elements. The idea is to show each element of the list as a individual choice in the ui, just like selectInput does in the ui.
I wrote an example with mtcars....
ANSWERAnswered 2021-Apr-08 at 07:48
selectInput on the server side.
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
carb. Looking at the data visually, it would probably be Toyota Corolla (high
vs 1, low
carb), Cadillac Fleetwood (low
vs 0, medium
carb) and either Maserati Bora (low-med
vs 0, high
carb) or Ferrari Dino (medium
vs 0, med-high

I 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:
I have a data frame with several columns and I want to recode values. Each column has its individual set of recoding rules, given in a table of
replacement mapping (each table is specific to each column).
I'm trying to come up with a programmatic solution that will allow me to functionize such recoding procedure.Example

Map is a good candidate here:
Due to lack of funds (till subscriptions can be taken again) we cannot pay for a developer to correct the way results are displayed in some query/searches.
What happens in these cases is that the order in which the rows are stored in displayed for the user.
Requirement As an interim - carry out the AlphaNumeric reorder the table of results so that the positions of each even is in Aplhanumerical order 1 to 10 then 11 and larger numbers below followed by alphabetical letters.
This is an example of how it can appear...

Pos column seems to be alphnumeric so numbers will not sort by value.
Let's say I want to apply the same function (
dplyr::filter) on the same dataset with different filtering conditions.
I can use
pmap here to give a list of arguments in
.l and the function I want to run in
.f. The arguments to
.data (which I have specified), and it works with one condition, as expected:
ANSWERAnswered 2021-Jan-30 at 08:17
If you are expecting 2 data frames, then using
list(mtcars) is not the correct approach. As suggested by @GregorThomas,
map is what you want to use instead. The element of your code that changes is the values that you would like to use for filtering, so this is what you should "map" instead:
How to recode some dataframe values to
NA if they don't appear in a separate vector?
More specifically, how to approach such task when:
- each data column to clean has its specific set of "valid" values to keep, independent of other columns
- column-specific values are given in a separate table (as vectors nested in a list-column in a

my_mtcarsthat does not appear in
table_valid_values, no cleanup is needed.

You can use Javelin like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the Javelin component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
