De-duplicating and Modifying Big Query Tables using Standard SQL
Big Query De-duplication and Category Modification using Standard SQL In this article, we will explore the process of de-duplicating a table in Google Big Query while modifying certain columns based on specific conditions. We will use standard SQL to achieve this without relying on external tools or scripts. Problem Statement Imagine you have a table with multiple rows containing different combinations of origin and food items. You want to remove duplicate entries where the origin and food combination appear together more than once, effectively concatenating their respective categories into a single value.

Mastering SAS Summary Function: Tips and Tricks for Precise Results
Table Variable Minimum Value Maximum Value V1 -3.70323584 3.56810079 V2 6.790622e-05 499931 V3 2.497735e-01 7.502424e-01 Notes The summary function uses the default setting for digits, which is determined by the global option "digits". This option can be set to change the default behavior. When passing a value to the summary function, it overrides the global option and sets the precision accordingly. In this case, specifying digits=10 resulted in unexpected behavior. Advice Be aware of how the summary function handles the digits argument and its interaction with the global option "digits".

Solving Data Frame Merger and Basic Aggregation using R
To solve this problem, you can follow these steps: Create a new column with row names: For each data frame (df1, df2, etc.), create a new column with the same name as the data frame but prefixed with “New”. This column will contain the row names of the data frames. Create a new column in df1 df1$New <- rownames(df1) Create a new column in df2 df2$New <- rownames(df2) Create a new column in mega_df3 mega_df3$New <- rownames(mega_df3)
