Re: [R] R-Size Limit (Confused)

2011-05-27 Thread Orvalho Augusto
I do not know what problem might be. But I recommend to go back to the excel
file, import it into MS Access. Then make an ODBC connection to the access
file. From which you will connect from R using RODBC.

  Hello,

 I've been banging my head against my monitor for some time now trying to

 =My GOAL==

  import a 4 column, 8,000 row table into R including headers.


 =WHAT I'VE ATTEMPTED==

 Original data was in Excel format.

 Converted data to both a .txt and .csv (to see which worked better)

 Imported data into R via commands as object demand (see below)

 Please excuse the long file path.

 demand=read.delim(C:\\Documents and Settings\\E066582\\My
 Documents\\R\\R-2.13.0\\bin\\demand.txt, header=T)



 demand=read.csv((C:\\Documents and Settings\\E066582\\My
 Documents\\R\\R-2.13.0\\bin\\demand.csv)

 ==PROBLEMS==

 In both cases, about half to three fourths of my data shows up as

 object demand with about 4000 lines. My headers also fail to appear.
 When my data is imported into R and I type the object name to bring it
 up I receive a memory usage error.

 ==SOLUTIONS

 I've gone in and cleaned up my data, making sure there are no (') or (#)
 but it could still a formatting issue

 My computer has 1.9GB RAM.  I have looked but I can't figure out how to
 increase R memory usage.

 Any ideas would be appreciated. If someone needs more information to
 help me I'll supply it.


 The information needed to address this is a public path to a place where
 one of those files resides.

 The problem is almost certainly not related to memory size. That is a tiny
 file. You could also cut and paste the first 20 lines into a message. Maybe
 there is something in the contents of the header that is the problem.
