While accessing to CSV file from disk with the help of the R program, where a path to the CSV file is provided in the configuration file ( A path is like "testData/Amazon S3/Inventory/Accounts.csv" which is provided in the Configuration file and cfig[2]$save.location is variable who is having value of this path accessed from Configuration file). Few lines of code are below
path <- cfig[2]$save.location
test_data <- fread(path,stringsAsFactors = FALSE,drop=col_ignor,blank.lines.skip = TRUE)
but it gave the message below:
Taking input= as a system command ('testData/Amazon S3/Inventory/Accounts.csv') and a variable has been used in the expression passed to
input=. Please use fread(cmd=...). There is a security concern if you are creating an app and the app could have a malicious user and the app is not running in a secure environment; e.g. the app is running as root. Please read item 5 in the NEWS file for v1.11.6 for more information and for the option to suppress this message.

when the following line of code executes,
config[4]$save.location <- stri_replace_all(config[4]$save.location, cp_val, fixed = cp_key)
It gives an error like as, Error in [<-.data.table(*tmp*, j, value = list(TestCaseID = "C419760", : Supplied 14 columns to be assigned 15 items. Please see NEWS for v1.12.2.
The above error was a warning but after manually updating of packages. This warning turns into an error. What will be the reason behind this issue and how to solve it? Thanks for Advance!!!
