Bit of a newbie for R, R Studio and Markdown but I am trying to use the render() function on my Rmd file and I get the following error:
Error: could not find function "render"
If I try to use the following I get this error:
markdown::render("MarkdownExample.Rmd")
Error: 'render' is not an exported object from 'namespace:markdown'
Still yesterday I could use the render fonction without any problem. Would anyone know what to do?
Thanks in advance
Shouldn't it be rmarkdown::render?

In R studio, I entered the following code:
summary(chickwts)
attach (chickwts)
barplot(chickwts$weight,main="Individual Weights,ylab="Weight")
Am using R 4.2.2 for Windows in R Studio environment. Code was from a course in TGC called "Learning Statistics, Concepts and Applications in R". Error message says comma the problem but this is the code that the course give. Am not sure how to proceed to get the barplot.
Any help appreciated.
I used the code the course gave, and it didn't work.

I trying to use following piece code in R Studio and I'm expecting a result that calculates b for 1:3 times.
for(b in 1:3){+cat(b,"+",b,"=",b+b, "\n")+}
However I keep getting an error:
Error: unexpected '}' in: "cat(b,"+",b,"=",b+b, "\n")+}"
Can anyone help please?
It expects something to add, but there is nothing to the right hand side of +.

I am new to r and am taking a basic course in which the identical code below is run without issue but when I try to run it I get the error below. Any help in resolving this would be much appreciated.
polling <- read.csv(file="C:/Users/njm3546/Desktop/xxx/PollingData.csv", header=TRUE, sep=",")
Summary(polling)
Error Message
unable to find an inherited method for function ‘Summary’ for signature ‘"data.frame"’
R is case sensitive and the function you need is summary (lowercase s).

Looking to read in an .xlsx file. This is an assignment so I specifically can't use Excel first to convert it to .csv.
Tried using read.xlsx which couldn't be found so I tried 'library(xlsx)' which was not a package according to R.
Does anyone know if there's something glaringly obvious that I'm not doing? Is the package called something different? Is there a different/better way to read an xlsx file?
Thanks!

I am returning to some old code where I had used the following syntax:
y[df$myvar %between% c(1,100)]
but get the error
could not find function "%between%"
This code used to work, and I have updated R in the mean time. any thoughts?
As Pascal pointed out, you should load the package data.table first:
library(data.table)
Then you'll be able to use it.
