I execute the below line in RStudio to append a text to myfile.rds
, which contains only one column named X
write("mytext", file = "myfile.rds", append = TRUE)
It executes without throwing any error or warning as shown below
> write("mytext", file = "myfile.rds", append = TRUE)
>
However, when I import the myfile.rds
dataset to view it the text is not added and I get the following warnings.
> myfile <- read.table("D:/.../.../myfile.rds", header=TRUE, quote="\"")
There were 12 warnings (use warnings() to see them)
> View(myfile)
On executing warnings()
, the below warnings are displayed:

I tried to append the same text to a new .rds
file and the text is successfully appended. Any suggestion on how I can fix this? Unfortunately I am not in a position
to share the contents of the myfile.rds
file due to privacy issues.
