I have received an .rdata file with what I think should be a list of co-ordinates (x,y) and their corresponding gray value; however, I do not know exactly the data type/format within the .rdata file. Is there a way for me to read these data without R? I do not have access to R. I have Excel and Matlab on a Mac. Please help. Unfortunately, I am not allowed to pass on the data (my Googling tells me someone familiar with R can export the data into a text of csv file easily).
Thank you in advance.
I downloaded R, read the .rdata in using load() and saved it out again using write.csv().

I'm trying to get R to read data from a txt file, but the file is not properly made, so it's giving me lots of errors.
Ideally, I'd like to be able to extract a dataframe to be able to work with from this, but I trully don't know how to.
The files are all in this link.
An example with any of them would work.
Thanks a lot!
I've a lot of .hyper files to work with. Most of the time I work with them using Python (using tableauhyperio lib), but I need to read them in R and I could not find a way to do it. Does anyone know some way to read hyper files in R?
Right now I'm reading the data in python and exporting them as csv to read in R the csv files...
I've been trying to create some graphs with the Shiny for R, I used this finished example, right here :
http://shiny.rstudio.com/gallery/telephones-by-region.html
But there is one problem : data is being scanned from the library file.
I tried to create my own library file with the data.
And there comes another problem : my data is taken from .csv file,
My question is : How can I create package file, that is just a data taken from the .csv file?
Thank you so much for your help

I've got a netCDF data file.The file can be downloaded at:
http://www.nodc.noaa.gov/OC5/WOA09/pr_woa09.html
It's the one called WOA09 netCDF version.
I want to use only climatology data (variable 4) and the first depth range [ , ,1] so I've used the code below so far in R. In now want to have the subset called MyData in RData format.
I want to convert it to RData to be able to play around with it in R. I haven't found anything on the internet about doing this, is it even possible? How?
Thank you so much if you can help! And let me know if I haven't given enough info .
library(ncdf)
MyFile<-open.ncdf("/home/et1211/wspd.mean.nc")
MyFile$var[[4]]->var4
MyData<-get.var.ncdf(MyFile,var4)
MyData<-MyData[,,1]
It's simple. You just save the object from R and use .RData as extension:
save(MyData, file="myNCDFdata.RData")
Or else you can read the ncdf data to an empty workspace, do whatever transformations you need, and then quit R and click ok to save workspace.
How can I read and write the following file using R ?
https://www.dropbox.com/s/vlnrlxjs7f977zz/3B42_daily.2012.11.23.7.nc
In other words, I would like to read the "3B42_daily.2012.11.23.7.nc" file and write with the same structure that it is written.
Best regards
Package ncdf have functions to do this. You should also read other Q&A on this site tagged with netcdf and r.
Basically to read a netcdf file:
library(ncdf)
a <- open.ncdf('your/path/to/your/file.nc') #that opens a connection to the file
Then function get.var.ncdf helps you extract the data, variable by variable.
The process to write one is described in this Q&A.
The idea is to create dimensions first using dim.def.ncdf then the variables with var.def.ncdf and finally the file itself using create.ncdf.
