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 5264I 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.Spencer Graves ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
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.
