maacs dataset

alfakini opened this issue 11 years ago · 24 comments

Hi, where could I get maacs dataset? I see you use it on 04_ExploratoryAnalysis/ggplot2/ggplot2_p2.Rmd, but the file isn't in the repository. I am coming from the Computing for Data Analysis on Coursera, there are a lot of people there trying to find the maacs dataset to try the examples presented on the lectures: https://class.coursera.org/compdata-004/class/search?q=maacs#11-state-query=maacs&11-state-filter=all&11-state-page_num=2

Thanks,
alf.

Just a second here that a link or reference to the data would be nice.

Answer 2 · 2014-05-11T21:32:17.000Z

Okay, here goes:

The data is in this RDS file: https://github.com/jtleek/modules/blob/master/04_ExploratoryAnalysis/PlottingLattice/maacs_env.rds

This file opens the data are draws a big set of panels of the level of allergen in the air for each subject over 5 visits (lines 201-204): https://github.com/jtleek/modules/blob/master/04_ExploratoryAnalysis/PlottingLattice/index.Rmd

Answer 3 · 2014-05-15T08:32:23.000Z

The MAACS dataset has no "eno" field as shown in ggplot2 slide (Roger Peng' Exploratory Data Analysis course). Have any ideas why ?

Answer 4 · 2014-05-16T22:07:31.000Z

You may load the whole data set with eno from here:

https://github.com/TarekDib03/ExploratoryDataAnalysisCoursera/blob/master/maacs.Rda

Let me know if you get any questions!

I appreciate your upload. This will help me practice with the ggplot2 videos.

Answer 10 · 2014-12-02T06:56:11.000Z

In the dataset I'm not finding logpm25, NocturnalSympt and also few other attributes..

Answer 11 · 2015-01-12T22:22:19.000Z

I also want to point out that data used in lecture have no corresponding dataset we can use, and data set prowided above does not contain some of the columns that where shown in lecture

Answer 12 · 2015-02-10T03:16:43.000Z

Jtleek has used maacs dataset for ggplot2 example.. but above link do not have attributes used in it. attributes like bmicat, NocturnalSympt, logpm25.. do anyone have any idead wr to find it..

Answer 13 · 2015-04-20T09:13:10.000Z

Do we have any updates here?

Answer 14 · 2015-05-03T20:46:11.000Z

There are some columns missing in the maacs data set, more specifically those needed for 3 - 7 - ggplot2(part 5)[8_11].mp4 video.

I found the data set in here: https://github.com/TarekDib03/ExploratoryDataAnalysisCoursera/blob/master/maacs.html
But I cannot load the data set with the error message: "more columns than column names"

Answer 15 · 2015-05-03T21:16:18.000Z

try this code to save all columns from the original data set (https://github.com/jtleek/modules/blob/master/04_ExploratoryAnalysis/PlottingLattice/maacs_env.rds):
env <- readRDS("maacs_env.rds")
id <- 1:750
maacs <- data.frame(id, env)
save(maacs, file = "maacs.rda")

Jtleek has used maacs dataset for ggplot2 example.. but above link do not have all attributes used in it. For example, attributes like bmicat, NocturnalSympt, logpm25, and so on. Does anyone have chance to get it?

Answer 17 · 2015-07-21T11:12:55.000Z

Best as I can tell, you can't get the dataset that contains bmicat and NocturnalSympt for this part of of the lecture. I found the quote below from http://lib.psylab.info/files/Peng2015b.pdf

"NOTE: Because the individual-level data for this study are protected by various U.S.
privacy laws, we cannot make those data available. For the purposes of this chapter, we
have simulated data that share many of the same features of the original data, but do not
contain any of the actual measurements or values contained in the original dataset."

If someone finds this dataset, I'd love to recreate the plots in the second part of the lecture.

Answer 18 · 2015-09-15T08:50:04.000Z

Use THIS: https://github.com/lupok2001/datasciencecoursera/blob/master/maacs.Rda

The variables are simulated. When run with the R Code from the ggplot2 lectures it gives slightly different graphs, but it works.

thanks lupok2001! it worked for me

Answer 20 · 2016-04-08T17:58:16.000Z

Thanks TarekDib03, your contribution was very useful.

Answer 21 · 2017-11-04T18:14:51.000Z

Thank you guys, is a great help to find the data here.....Otherwise cannot practice. Cheers

I loaded it with these steps:
url = "https://raw.githubusercontent.com/lejarx/MAACS-dataset/master/maacs.rda" destfile = tempfile(fileext = ".rda") download.file(url, destfile, method = 'libcurl', mode = "wb", quiet=TRUE) load(destfile) unlink(destfile)
