Set col_names to FALSE...???

I don't have access to Excel, so can't test this.
I have a suspicion that the problem is not readxl.
But rather the "as.data.frame" step.

My assessment was and is likely correct.
My error was in writing the wrong function name... should have been read_excel
whose parameters need to be adjusted to not look for a header line.

Hi R users,
I was trying to create a pivot table for the following data, in which I
wanted to put "id" in rows and "ObsSite" in columns and "Obsdate" is in
the cells.
I used the following code but it took only one date among the two dates.
For example, the animal (Id2) which was observed in the s

Colleagues,
I'm using readxl and dplyr to extract a specific cell from all worksheets in a
directory.
All of these worksheets have the same physical layout.
Issue 1: Minus sign replaced by an X after data extraction.
library(plyr)
library(readxl)
files <- list.files(pattern="*.xls", full.names

Try posting this at the RStudio Help site, as R Markdown is part of the
ecosystem they have created and support.

Hi,
In R, we know how to autocomplete a function name or some arguments in the
function. I usually use “Tab” to achieve this.
But when I was preparing my math homework using R Markdown, I want to achieve
similar results: for example,
I want to autocomplete $\frac{}{}$ when I only typed $\fr$
I tried to solve the task via following code:
manyorders <- replicate(100, sample(colnames(dat)), simplify=FALSE)
all_results <- lapply(manyorders, function(ord) {
tmpdat <- `colnames<-`(dat, ord) # copies and renames in one line
corfit <- duplicateCorrelation(dat, block = targets$Subject)
17 matches
