R help - Aug 2017 - How to convert .Rdata file into .csv or something else?

Dear mailing list members,

I am a beginner of this community.

I would like to analyze data in a .rdata file.
I ran the following code, but the object "d" remained empty.

d <- load("~/docdis/input/ch2/WV6_Data_R_v_2016_01_01.rdata")

I would like to know how to convert this file format into .csv or .txt.
I suppose this question is very basic, but I could not find solutions on
internet or in my textbooks.
I would appreciate it if someone would help me.

Welcome to the forum
.Rdata may contain many different objects.
I would suggest doing a? "ls()" to see what objects you have.
then have a look at ?write.table or ?write.csvThese commands will write many
types of objects to a .csv file.
For example if I have a data.frame called "dat1" I can write it to a
csv (text) file like this:
write.csv(dat1, "~/Rjunk/mydata.csv")

Hi Yohei,
Were there any error messages that indicated that the file could not
be found? As you are using a *NIX operating system, remember that
".rdata" is not the same as ".Rdata". What does:

file.exists("~/docdis/input/ch2/WV6_Data_R_v_2016_01_01.rdata")

return?

... and load() writes those directly into your workspace.  (You can 
control where it writes, but that's the default.)

Adding the "verbose = TRUE" argument to load() will tell you what
you've
just read.

The variable d should have contained the names of objects from that 
file.  If it was empty, then something went wrong.
