@dario I believe it does not because the value labels for my dataset are in one cell for each variable. It helps if you simplify your codes data: Then, for example, on a single column you can do: One way to apply it across columns given your example data is to use sapply: (Note this specific example assumed all column names in codes for variable x (in df) is x_values, as in your example data).

To append the df2 data frame to df1, use the rbind() function. In this tutorial, we learned how to append a single row (or multiple rows) to a DataFrame in R or how to insert it (or them) at a specific index of the DataFrame. Sure, then one should do. To append one row to a DataFrame in R, we can use the rbind() built-in function, which stands for "row-bind". In this example, we first defined and printed the data frame and then defined a vector that will act as a column when we will add to the data frame, and using the $ symbol, and we appended a column to the data frame. Etc. So lets use that data frame to illustrate how to append data frames. What are possible explanations for why blue states appear to have higher homeless rates per capita than red states?

New replies are no longer allowed. Not the answer you're looking for? deformer graphs can now receive input, bind to, and receive data from, multiple actor components as inputs. While base R does do grouping operations, I find them to be slightly less intuitive/flexible than when using the data.table or dplyr packages, so I'll stick with those two for the processing here (and leave you to determine which if either you wish to use, and then adapt your processing to do it group-wise). To learn more, see our tips on writing great answers. The data frames dont have the same number of columns. You should never ever ever iteratively rbind within a loop: performance might be okay in the beginning, but with each call to rbind it makes a complete copy of the data, so with document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits.
