Here is a list of the terms and definitions on each card. This step creates the three columns of codes preserving hierarchy in the structure required for plotly treemap.This is an alternate content page containing a Flash Card Activity. Into = c("l1node", "l2node","l3node","l4node"),Ĭreate ids, labels and parents columns for treemap plot. # this excludes autocoded nodes (can be selected when exporting data from NVivo) I provide the replicable steps below with codes on data from NVivo’s built in example project.įirst, read data into a new dataframe, clean it a bit, remove unnecessary columns, unnecessary strings from the Codes column, and split hierarchical nodes (coding terms) into separate columns. This is the only tricky bit in this workflow as the data from NVivo needs some processing in R to the structure needed for a treemap plot using plotly package. Importing data into R and structuring the df for plotly treemap plot This is the default treemap you get in NVivo. Below two screenshots of Mac OS version of NVivo showing the treemap and underlying data that could be exported. Microsoft Excel format) if you use Mac version of NVivo then you can export data as. You basically have two options: if you use Windows version of NVivo then you can export data as. Once you are in R, you just need the packages tidyverse, plotly and RColorBrewer for the codes below to run successfully. So, I decided to export coding data that NVivo uses to produce these charts and use plotly package in R to create customisable treemap plots. The problem is I can’t do much with what NVivo provides in the way of these charts except to change colours, that too within the limited options available. While latest versions of NVivo do come with quite a few options for visualisation, “treemap”, which you can get through Hierarchy Chart option in NVivo is my favourite. I’ve been coding qualitative data in NVivo for my research for the last few weeks, and one of the things I like doing as soon as I have done decent amount of coding is to visualise them in some way. First, read data into a new dataframe, clean it a bit, remove unnecessary columns, unnecessary strings from the Codes column, and split hierarchical nodes (coding terms) into separate columns. Basically, you can make much better treemap plots using plotly package in R using the coding frequency data that you can export from NVivo. I provide the replicable steps below with codes on data from NVivo’s built in example project. TL DR This post is only interesting/useful if you work with qualitative data and want to customise the “treemap” you get in NVivo, one of the most commonly-used computer-assisted qualitative data analysis software (CAQDAS).
