#Reshape long stata manual#

The names in red specify the name of new variables. Pivot_longer(dfwide, starts_with('stub'), names_to = 'variable', values_to = 'value') in Stata might lead readers to suggest a reshape long, which could be a good idea. Reshape long stub, i(id) j( variable) string papers that link the use of Stata commands or programs to associated. results to reshape 8 to 31 times faster in wide-to-long reshapes and 2 to 13.

In contrast, in R, columns with different types are coerced to their higher type (logical RESHAPING DATA WIDE TO LONG This module illustrates the power (and simplicity) of Stata in its ability to reshape data files. A new command, sreshape, supports sparse and speedy reshaping of data. When string columns are append too numeric columns, Stata returns an error (and with the option force, it replaces the using dataset to missing values). Wen there are multiple matches both in the master and using datasets, these functions create all combinations of rows, similarly to Stata joinby (and contrary to Stata merge m:m). The following table gives the correspondence between the Stata commands merge and joinby with the dplyr functions: Stata

the syntax diagram for the command in the manual and in the. We will only keep the variables 'cname', 'year', 'fhstatus' (democracy status) and 'unnapop' (population), and only the years 20. To make it a little bit easier to grasp we will throw away most of the variables. It holds data on the countries of the world, over time. thus the variable names inc60, inc70, inc80, and inc90 all share the stubname inc. and where stubnames are variable names (longwide), or stubs of variable names (widelong), and either way, may contain, denoting where j appears or is to appear in the name. Reshape from long to wide First we load the data to work with: The QoG institute time-series cross-section data. The packages dplyr uses the SQL concepts of left, right, full, inner, semi, anti and cross joins. a key point is that in reshaping from wide to long, reshape expects to find one or more groups of variables so that names in each group all begin with the same stubname.
