All I want to know at this pointis, is whether my way of getting the definitions in the environment "clumsy" and whether there are better ways to do it. Yes, you mention "attr..." but that is not as simple as viewing it in RStudio's environment pane. Thank you!

Hm. What do you mean by "clickable". #I can save any objects to a file save(mydata,definitions, file="test.R") rm("mydata", "definitions") #load them back load("test.R") #but it does not make them "clickable".

Now I realize expss may not be what I need. I have now written a self- runnable, replicable set of codes (listed below). Perhaps that gives an idea of what I need.

For instance, if you do this: library(prettyR) describe(mtcars) you get this: Description of mtcars Numeric mean median var sd valid.n mpg 20.09 19.20 36.32 6.03 32 cyl 6.19 6.00 3.19 1.79 32 disp 230.72 196.30 15360.80 123.94 32 hp 146.69 123.00 4700.87 68.56 32 drat 3.60 3.70 0.29 0.53 32 wt 3.22 3.33 0.96 0.98 32 qsec 17.85 17.71 3.19 1.79 32 vs 0.44 0.00 0.25 0.50 32 am 0.41 0.00 0.25 0.50 32 gear 3.69 4.00 0.54 0.74 32 carb 2.81 2.00 2.61 1.62 32 However, you can call almost any summary function as an argument to describe. Suppose I wrote a function "fackey" that produced this output on a factor variable "city": fackey(city) label numeric count New York 10 30 London 15 23 Paris 16 22 Rome 20 25 So if you ran "describe" on your data frame, you would get a list of summary data frames that could be saved with the data frame in an .Rdata file.

Sorry I cannot explain myquestions well enough.All I was showing you was, right after loading the binary data file, I saw two data frames---data which contain the data, and desc which contains definitions of all variables (as shown in 2.jpg). This is a data file from the publisher and I wanted to know what it takes to create a binary data files along with definitions of variables, both in theenvironment.Steven On 2021/5/13 下午 09:51, PIKAL Petr wrote:Hi Steven I probably do not understand your question correctly. In 1 you show twoobjects "data" 14x42 data frame and "desc" which is 2x14 data frame, both residing in global environment.In 2 you show contents of data frame desc where variable are probablyvariable names which are also in data object.names(data) and label which is some more elaborate description of the variable. If you want to move this label into your data object you probably could use attr attr(data, "label") <- desc$label If the order of "variable" is same as the order of data columns. I do not understand what do you mean by - how to get that "desc" in there in the environment? It is already part of global environment. Youwant to create some new environment and move you desc there?Beside, your images are not familiar to me, this is plain R or some kind ofspecial GUI like R studio?Cheers Petr-----Original Message----- From: Steven Yen <st...@ntu.edu.tw> Sent: Thursday, May 13, 2021 1:37 PM To: PIKAL Petr <petr.pi...@precheza.cz> Subject: Re: [R] Variable labels Petr Thanks. I am sending this to you privately as I am sending attachment. 1. I load the binary file and see the data frame and what appears to be description (desc) alongside it (1.jpg). 2. Expanding "desc", I get to read the documentation (contents ofdesc).(2.jpg). #2 is all I need. I do not need to do anything fancy with the variable label. I just like my students to have a simple ways of learning the variables is the data file I provide to them. Again, my main question is, how to get that "desc" in there in the environment. Thanks.

What I need “appears” simple. The .RData file is provided by a third party (likely converted from a different data format such as SAS in which variable labels (not value labels) are common). When I load the binary file, in the “environment” I see, as expected, a data frame showing how many observations for how many variables. In addition, there is also an item (in the environment) (say “desc”) containing a list of variable labels (definitions). I simply like to know how to get “desc” in the environment—-it is a convenient way to show definitions of all variables when you send a binary data file to a third party.
