This is the description of the task. 1. Get the list of file names to process as a character vector. This is the input to this program. The example files, [login to view URL] and [login to view URL] are attached. In reality, there are about 12 files and the total number of records may be between 2 Million and 8 Million. For example, in this case, the list of files will be [login to view URL] and [login to view URL] 2. Read each of the files into a data frame. Then rbind the dataframes into one single data frame. Let us call this data frame “all”. 3. For each column in the dataframe (names(all)), which of the names (columns) satisfy this property? a. All values are blank b. All values have the same value. Of course, the answer from a. above will also be included in this set. So, my interest is this: which of the columns have all blank values and which of the columns have all the same value? I would do this in dplyr but your choice may vary. I would like to get this done now if possible. I will upload the real files later. Thanks, Satish

Hi, I have vast experience using R for data acquisition, preparation and model building. Since you have large files, I can assist you in importing the data efficiently. Then I can employ the most efficient methods to determine missing values and homogeneity (all same values) in columns. Regards, Chris

Hi Mr. Satish Thank you for posting this project. I could help you. I think your idea is okay with dplyr , but maybe I will think about an customize solution... I think I need about 10-12 hours for this job. I could start now and get it done before weekend. Looking forward to hearing from you! Thanks & B/R
