Hello,
R 4.0.2 on Ubuntu 20.04 LTS, sessionInfo below.
I'm also unable to read the file with Rscript from the Ubuntu terminal
but the error is not the same as the OP's.
The first try was a file test1.R with the following commands.

Hi Andy:
I just checked in "options", and the following appears:
$stringsAsFactors
[1] FALSE
I think this might be it.
You may want to look at options() in R-3.6.1.
Thanks,

Read the NEWS about R4.0.0 [1] (search for stringsAsFactors), or read any of
the many announcements in blogs and forums around the Internet.

Hi Andy,
I believe this is because R 4.0 has changed the default behavior of
data.frame().
Prior to 4.0, the default was stringsAsFactors=TRUE.
In 4.0, the default is stringsAsFactors=FALSE.
If you run your code in R 3.6.1 and change the command to
data <- data.frame(name,values,stringsAsFactors=

Hello,
Yet another way, with package lubridate.
When creating the "Date" objects, I set day = 1 to compare to TRUE below.
library(lubridate)
start <- as.Date(ISOdate(1861, 1, 1))
end <- as.Date(ISOdate(2005, 12, 1))
start + months(4139 - 2400)
#[1] "2005-12-01"
end == start + months(4139 - 2
Hi Milu,
Jim gave a good solution. Another approach is to use standard packages
and objects.
In particular 'ts' (time series) objects from the stats package, and
'xts' (extensible time-series) objects from the xts package.
library(xts)
# construct dummy data
z <- rnorm(36)
# convert it into a mont
