kandi X-RAY | pct Summary

pct is a R library typically used in Artificial Intelligence, Machine Learning, Deep Learning, Tensorflow applications. pct has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

The goal of pct is to increase the accessibility and reproducibility of the data produced by the Propensity to Cycle Tool (PCT), a research project and web application hosted at www.pct.bike. For an overview of the data provided by the PCT, clicking on the previous link and trying it out is a great place to start. An academic paper on the PCT provides detail on the motivations for and methods underlying the project. A major motivation behind the project was making transport evidence more accessible, encouraging evidence-based transport policies. The code base underlying the PCT is publicly available (see github.com/npct). However, the code hosted there is not easy to run or reproduce, which is where this package comes in: it provides quick access to the data underlying the PCT and enables some of the key results to be reproduced quickly. It was developed primarily for educational purposes (including for upcoming PCT training courses) but it may be useful for people to build on the the methods, for example to create a scenario of cycling uptake in their town/city/region.

            If I understand you well, you want the running percent change with respect to the last value of the previous year. It’s maybe not the most elegant, but you can explicitly build this last-value-of-previous-year series.

            To start, you build a series with the date indices and years as values:

            VBA/Excel – calculate date then adjust if weekend or holiday
            Asked 2021-Jun-04 at 10:31

            What I'm trying to achieve:

            • Create a formula that calculates a deadline date using four variables : StartDate, Over2%Date, Percentage, Currency
            • If Percentage < 2%, the function should first calculate (StartDate + 120)
            • If Percentage >= 2%, the function should first calculate the lesser of (StartDate + 120) and (Over2%Date + 30)
            • The resulting date cannot fall on a weekend or a holiday, so the function should subtract days until a valid working day is found.
            • The range containing the list of holidays to check will vary depending on Currency

            Python time series - count periods below/above and threshold for specified minimum duration
            Asked 2021-May-27 at 13:02

            In a pandas time-series, I am trying to find a combination measure of a threshold with a duration.

            For instance, we want the number of periods > 5 minutes, where column ['pct'] is below 80

            The dataframe looks like this:

            timestamp pct 27-05-2021 10:11 95 27-05-2021 10:12 94 27-05-2021 10:13 80 27-05-2021 10:14 94 27-05-2021 10:15 80 27-05-2021 10:16 80 27-05-2021 10:17 80 27-05-2021 10:18 80 27-05-2021 10:19 80 27-05-2021 10:20 91 27-05-2021 10:21 NaN 27-05-2021 10:22 80 27-05-2021 10:23 80 27-05-2021 10:24 80 27-05-2021 10:25 80 27-05-2021 10:26 94

            It would thus need to identify 1 period(as we do not care to include NaN values)

            I've gotten some of the way with the post from Ben B, and the answer from Alain T here: How to count consecutive periods in a timeseries above/below threshold?

            I've attached an ugly image from microsoft paint to illustrate the problem

            NB: It is quite a big dataframe, so I am not sure that iterating over the dataframe is the best idea, but any help is very much appreciated.

            Assuming that the input is unquoted, convert to symbol with ensym, evaluate (!!) within group_by while converting the symbol into a string (as_string) and paste the prefix '_pct' for the new column name. In mutate we can use := along with !! to assign the column name from the object created ('colnm')

            create function my.render.cat with comma decimal separator instead of point in r
            Asked 2021-May-26 at 03:42

            I am trying to create a function to get frequencies and proportions for a table1 with this code

            my.render.cat <- function(x) { c("", sapply(stats.default(x), function(y) with(y, sprintf("%d (%0.0f %%)", FREQ, PCT)))) }

            but when I apply it to the function table1() I get the results for proportions with decimal point instead of comma.

            I've tried with options(OutDec= ",") but nothing changes Nor by changing Sys.locale for LC NUMERIC.

            I've also tried with format(table1, decimal.mark=",") but it doesn't work for table1 output

            any suggestions?

            I add a reproducible example using iris dataset and formatting Sepal.length to be able to calculate proportions.

            table1::table1(~factor(Sepal.Length) | Species, data = iris, render.categorical=my.render.cat)
