...and then update with read.csv.sql.? Any example code will be really helpful. 2. If we use the H2 database instead of default sqlite and use the readcsv option, will that be faster and is there a way we can specify the above thought of applying a DF class to table column properties and update with CSVREAD library(RH2) something like SELECT * FROM CSVREAD('C:/JP/Temp/2008.csv') Any example code will be really helpful. 3. How do we specify where the H2 file is saved. Saw something like this, when I ran this example from RH2 package, couldn't find the file in the working directory. con...

Hi, I do have < INT_MAX. This looks attractive but since they are unique identifiers, storing them as factor will be likely to be counter-productive. (a string version + an int32 for each) I was looking to https://cran.r-project.org/web/packages/csvread/index.html This looks like a good feet for my needs. Any chances such an external package for int64 would be integrated in core ?

Dear all: I have two larges files with 2000 columns. For each file I am performing a loop to extract the "i"th element of each file and create a data frame with both "i"th elements in order to perform further analysis. I am not extracting all the "i"th elements but only certain which I am indicating on a vector called "d". See an example of my code below

Well I definitely cannot use them as numeric because join is the main reason of those identifiers. About int64 and bit64 packages, it's not a solution, because I am releasing a dataset for external users. I cannot ask them to install a package in order to exploit them. I have to be very carefull when releasing the data. If a user just use read.csv functions, they by default cast the
