[R] ggplot error of "`data` must be a data frame, or other object coercible by `fortify()`, not an S3 object with class rxlsx"

officer redefines the read_xlsx command.  You should have got a message to
that effect when you loaded the officer package.  You can use the version
from the readxl package with

readxl::read_xlsx()  command.

[R] ggplot error of "`data` must be a data frame, or other object coercible by `fortify()`, not an S3 object with class rxlsx"

This illustrates many things but in particular, why there is a difference
between saying you tried:

 

    class(eth)

 

And saying the function you (think you) called is documented to return a
data.frame.

 

Just typing something asking for the class would rapidly have shown it was not a
data.frame and also what it was. True, having multiple packages in some order
overlay each other is a bit subtle for some and I am glad quite a few people
here noticed it.

 

It may indeed make sense to more fully specify package::function notation in
anything you let others use as they may indeed load more packages ?

officer redefines the read_xlsx command.  You should have got a message to that
effect when you loaded the officer package.  You can use the version from the
readxl package with

 

readxl::read_xlsx()  command.

 Hi all,

when I submitted the following code, the Eth is data frame. I can see 14 obs. of

library(readxl)

eth <- read_xlsx("c:/temp/eth.xlsx")


but when I add more package (see below,) the Eth is "List of 1"
library(readxl)
library(ggplot2)

But I need those package in future. Is there a way to fix the problem?

  Hi All,
1. the eth is a data frame (not sure that based on error message?) that I load
it from excel file. Here is the code: eth <-
read_xlsx("c:/temp/eth.xlsx")
2. I try to use the code to convert eth into eth2, but I got error
message:> eth2 <- data.frame(eth)Error in as.data.frame.default(x[[i]], optional = TRUE, stringsAsFactors =
stringsAsFactors) :
  cannot coerce class ?"rxlsx"? to a data.frame

So, it seems the data.frame can not do this data convert? Do you know which
statement/function can do this?


thank you for your help.

 Kai,

The answer is fairly probable to find  if you examine your variable
"eth" as that is the only time you are being asked to provide the
argument as in "ggplot(data=eth, ..) ...)

As the message states, it expects that argument to be a data frame or something
it can change into a data.frame. What you gave it probably is an object meant to
represent an EXCEL file or something. You may need to extract a data.frame (or
tibble or ...) from it before passing that to ggplot.

Hello List,
I got an error message when I submit the code below ggplot(eth, aes(ymax=ymax,
ymin=ymin, xmax=4, xmin=3, fill=ethnicity)) +  geom_rect() + 
coord_polar(theta="y")  +  xlim(c(2, 4)  )

Error: `data` must be a data frame, or other object coercible by `fortify()`,
not an S3 object with class rxlsx


I checked the syntax. But I can  not find any error on my code. Can you help me
to find where is the problem?

Thanks
