Hi all,
I found something, but I don't know why it happen.
when I submitted the following code, the Eth is data frame. I can see 14 obs.
of 2 variables
library(readxl)
library(ggplot2)
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)
library(dplyr)
library(magrittr)
library(knitr)
library(xtable)
library(flextable)
library(officer)
eth <- read_xlsx("c:/temp/eth.xlsx")
But I need those package in future. Is there a way to fix the problem?
Thanks,

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.

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