            How to produce a point graph in R like this?
            Asked 2021-Jun-16 at 04:05

            I have basically this very odd type of data frame:

            The first column is the name of the States (say I have 3 states), the second to the last column (say I have 5 columns) contains some values recorded at different dates (not continuous). I want to create a graph that plots the values for each State on the range of the dates that starts from the earliest and end in the latest dates (continuous).

            The table looks like this:

            state 2020-01-01 2020-01-05 2020-01-06 2020-01-10 AZ NA 0.078 -0.06 NA AK 0.09 NA NA 0.10 MS 0.19 0.21 NA 0.38

            "NA" means there is not data.

            How do I produce this graph in which the x axis is from 2020-01-01 to 2020-01-10 (continuous), the y axis contains the changing values (as points) of the three States, each state occupies its separate (segmented) y-axis?

            Thank you.

            You can get the data into a long format, which makes it easier to plot. R will make it difficult to read column names that start with a number. While reading the data, ensure that you have check.names = FALSE so that column names are read as is.

            If any of your output is going to be raw, you need to pass -r; it'll just be ignored for data items that aren't strings.

            Anyhow -- if you write (expr1, expr2), then your input will be passed through both expressions. Thus:

            Postgres: Count multiple events for distinct dates
            Asked 2021-Jun-15 at 17:04

            People of Stack Overflow!

            Thanks for taking the time to read this question. What I am trying to accomplish is to pivot some data all from just one table. The original table has multiple datetime entries of specific events (e.g. when the customer was added add_time and when the customer was lost lost_time). This is one part of two rows of the deals table:

            id add_time last_mail_time lost_time 5 2020-03-24 09:29:24 2020-04-03 13:20:29 NULL 310 2020-03-24 09:29:24 NULL 2020-04-03 13:20:29

            I want to create a view of this table. A view that has one row for each distinct date and counts the number of events at this specific time.

            This is the goal (times do not match with the example!):

            Combine values from duplicated rows into one based on condition (in R)
            Asked 2021-Jun-15 at 16:51

            I have a dataset with the name of Danish ministers and their position from 1990 to 2020 (data comes from dataset called WhoGovern; https://politicscentre.nuffield.ox.ac.uk/whogov-dataset/). The dataset consists of the ministers name, the ministers position, the prestige of that position, and the year in which the minister had that given position.

            My problem is that some ministers are counted twice in the same year (i.e., the rows aren't unique in terms of name and year). See the example in the picture below, where "Bertel Haarder" was both Minister of Health and Minister of Interior Affairs in 2010 and 2021.

            I want to create a dataset, where all the rows are unique combinations of name and year. However, I do not want to remove any information from the dataset. Instead, I want to use the information in the prestige column to combine the duplicated rows into one. The observations with the highest prestige should be the main observations, where the other information should be added in a new column, e.g., position2 and prestige2. In the example with Bertel Haarder the data should look like this:

            (PS: Sorry for bad presenting of the tables, but didn't know how to create a nice looking table...)
