Hello, All:
I'm getting strange errors with write.csv with some objects of
class c('findFn', 'data.frame'). Consider the following:
df1 <- data.frame(x=1)
class(df1) <- c('findFn', 'data.frame')
write.csv(df1, 'df1.csv')
# Error in x$Package : $ operator is invalid for atomic vectors
df2 <- data.frame(a=letters[1:2],
b=as.POSIXct('2024-06-28'))
class(df2) <- c('findFn', 'data.frame')
write.csv(df2, 'df1.csv')
# Error in tapply(rep(1, nrow(x)), xP, length) :
# arguments must have same length
"write.csv" works with some objects of class c('findFn',
'data.frame') but not others. I have 'findFn' object with 5264 rows
that fails with the following error:
Error in `[<-.data.frame`(`*tmp*`, needconv, value = list(Count =
c("83", :
replacement element 1 has 526 rows, need 5264
I have NOT yet been able to reproduce this error with a smaller
example. However, starting 'write.csv' with something like the
following should fix all these problems:
if(is.data.frame(x)) class(x) <- 'data.frame'
Comments?
Thanks for all your work to help improve the quality of
statistical software available to the world.

Hello,
I don't know if this answers to question.
I wasn't able to reproduce errors but warnings, yes I was.
A way of not giving errors or warnings is to call write.csv at the end
of a pipe such as the following.
df1 <- findFn("mean")
df1 |> as.data.frame() |> write.csv("df1.csv")
This solution is equivalent to the code proposed in the OP without the
need for a change in base R.
Thanks for this. Ivan Krylov informed me that this was NOT a problem
with base R but with "[.findFn". I fixed that and got help from Ivan
fixing another problem with "sos". Now it is officially "on its way to
CRAN."
Hope this helps,
Yes. I'm not yet facile with "|>", but I'm learning.
