row names are generally seen as a not great idea, and the tidyverse is not designed to handle them gracefully; If i was in your shoes I would be making a choice for this piece of work to
a) focus on base functionality, because for a special reason I must use rownames ; as a consequence make a plain data.frame and not a tibble.
b) continue with tidyverse and tibbles etc, and simply don't use rownames.
Actually my file has long numeric number in data sheet so if I read them using read.table as txt or csv file then it convert these numbers into scientific notation, so I was trying to read them as excel sheet.
now I was trying read excel with (readxl) R packages by making first column as row but it shows error?
If I don't have row names in this files then how to modify this below command to match with first column instead;
> all(rownames(targets) %in% colnames(mval))
will it be ok to use instead; to match first coulmn of this file with colnames of another file
> all(targets [ , 1 ]%in% colnames(mval))
