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.

QUESTION

append or join value from one dataframe to every row in another dataframe in Pandas

Asked 2021-Jun-15 at 23:59

I'm normally OK on the joining and appending front, but this one has got me stumped.

I've got one dataframe with only one row in it. I have another with multiple rows. I want to append the value from one of the columns of my first dataframe to every row of my second.

df1:

id Value 1 word

df2:

id data 1 a 2 b 3 c

Output I'm seeking:

df2

id data Value 1 a word 2 b word 3 c word

I figured that this was along the right lines, but it listed out NaN for all rows:

QUESTION

Aggregating all values not in the same group

Asked 2021-Jun-15 at 22:57

Is there a way in PostgreSQL to take this table:

ID country name values 1 USA John Smith {1,2,3} 2 USA Jane Smith {0,1,3} 3 USA Jane Doe {1,1,1} 4 USA John Doe {0,2,4}

and generate this table from it with the column agg_values:

ID country name values agg_values 1 USA John Smith {1,2,3} {0,1,3,1,1,1,0,2,4} 2 USA Jane Smith {0,1,3} {1,2,3,1,1,1,0,2,4} 3 USA Jane Doe {1,1,1} {1,2,3,0,1,3,0,2,4} 4 USA John Doe {0,2,4} {1,2,3,0,1,3,1,1,1}

Where each row aggregates all values except from the current row and its peers.
So if name = John Smith then agg_values = aggregate of all values where name not = John Smith. Is that possible?

You can use a lateral join to a derived table that unnests all rows where the name is not equal and then aggregates that back into an array:

Currently I have 3 tables like below

Master

ID_NUMBER ZIPCODE 1 12341 2 12342 3 12343 4 12344

Table1

ID_NUMBER CITYNAME COUNTYNAME 1 NEW YORK QUEENS 3 DETROIT SUFFOLK

My desired output is like below. I want to filter based on the zipcode from master table

ID_NUMBER ZIPCODE CITYNAME COUNTYNAME 2 12342 ATLANTA ROCKLAND

How would i go about writing a query for this? Below is what i have tried but it's giving me null values if the ID_NUMBER is not found on that particular table.

QUESTION

Coalescing multiple chunks of columns with the same suffix in names (R)

Asked 2021-Jun-15 at 20:10

I have a dataset with various "chunks" of columns with different prefixes, but the same suffix:

ID A034 B034 C034 D034 A099 B099 A123 B123 ... 1 NA 1 NA NA NA 3 1 NA ... 2 2 NA NA NA 2 NA NA 2 ... 3 NA NA 2 NA NA 2 1 NA ...

The number of columns within each "chunk" also varies. Is there any way (other than manually, which is what I have been painstakingly doing with coalesce(!!! select(., contains("XXX")))) to automatically coalesce by chunk based on the shared suffix? That is, the result should resemble

ID 034 099 123 ... 1 1 3 1 ... 2 2 2 2 ... 3 2 2 1 ...

I'm not sure how to begin doing something like this, so any suggestions would be very helpful.

We reshape the data into 'long' format with pivot_longer, then we group by 'ID' and loop across the other columns, apply the na.omit to remove the NA elements (we assume that there is only one non-NA per each column by group)
