Re: [R] how to read numeric vector as factors using read.table.ffdf

Please read the posting guide. Your question is far from clear. First you're apparently unhappy because character vectors are being converted to factors. Then later you ask how to tell a function that some numeric datas should be considered factors. Which is it that you want? A simple short

[R] how to read numeric vector as factors using read.table.ffdf

I have a big data set that includes character variables of many different values. I'm trying to use ff to read the data and then use biglm.big.matrix to build linear models. However, since big.matrix will convert all character vectors to factors and the character labels will be lost. I decided to

Re: [R] How to read a file with two data sets in text format

You have to sync up the data before you can do a scatter plot. If the data are changing slowly relative to the sample rates then you can use approx to interpolate one data set at the timestamps of the second to generate a column you can add to the second data frame.

Man, if that medicine doesn't cure you of wanting to create dozens of different objects in memory, I don't know what will. Let's see: 1) Creates a potentially large number of global objects with names unrelated to their content 2) Creates and updates a global variable for future race condition

Re: [R] how to read different files into different objects in one time?

The short answer is: don't try. You really don't want dozens of different objects in memory that you didn't name yourself. What you want instead is a list of objects. You can start with a vector of filenames and use lapply to create another list containing the data frames. For convenience you
