[R] Problem in generating any model with my dataset in R
Dear all, I am using kernlab function for analysis of dataset containing 8000 rows and 171 column, but getting an error saying cannot allocate the memory, It is running properly with the dataset having 3000 rows and 251 column, Also when I tried this with dataset having 7000 rows and 171 column getting error saying that "Error in terms.formula(formula, data = data) : '.' in formula and no 'data' argument" What can be done with this dataset, how can I use this for analysis. Is there any limitation ? please suggest me some solution. Thanks for your help, regards Bhawana Sahu [[alternative HTML version deleted]]
Hi Your objects are not so big, therefore I assume that something is wrong with their stucture, especially when one object gives you results. I wonder if you get more precise answer without providing some basic facts (structure of data, code, OS, R version).

Hi Why do you replace NA with meaningless ?-?? NA for R means Not Available and R can handle it properly. ?-? means ?-? for R and is treated as character together with rest of the column. If somebody aviced it to you, do not trust him any more. Anyway, you still do not provide info about data. If you have so many rows maybe the best way would be dput(head(yourdata[1:50,]) or something like that.

Dear Bhawana Sahu, You don't show any of the commands that you used to produce this error, so one can only guess at its source, but the error message you quote seems reasonably clear -- apparently, you failed to specify the data argument to the function(s) you called. For example, with a data frame named D containing a variable y among others, lm(y ~ .) will fail but lm(y ~ ., data=D) will work. If you *did* specify the data argument, then you'll have to provide more information about what you did, ideally including a small reproducible example. I hope this helps, John ----------------------------- John Fox, Professor McMaster University Hamilton, Ontario Canada L8S 4M4 Web: socserv.mcmaster.ca/jfox> -----Original Message----- > From: R-help [mailto:r-help-bounces at r-project.org] On Behalf Of Bhawana > Sahu > Sent: October 19, 2015 3:04 AM > To: r-help at r-project.org > Subject: [R] Problem in generating any model with my dataset in R > > Dear all, > > I am using kernlab function for analysis of dataset containing 8000 rows and > 171 column, but getting an error saying cannot allocate the memory, It is > running properly with the dataset having 3000 rows and 251 column, > > Also when I tried this with dataset having 7000 rows and 171 column getting > error saying that "Error in terms.formula(formula, data = data) : '.' in formula > and no 'data' argument" > > What can be done with this dataset, how can I use this for analysis.
