How to Import a CSV File in R

Importing data from csv File to R

I was using a work PC, and the files were encrypted - which was the reason why importing data into R was not working. I bypassed it by copying data into a text document.
Thanks everyone!

How do I import a CSV file in R?

You would use the read.csv function; for example:

dat = read.csv("spam.csv", header = TRUE)

You can also reference this tutorial for more details.

Note: make sure the .csv file to read is in your working directory (using getwd()) or specify the right path to file. If you want, you can set the current directory using setwd.

How to read a csv-file from an url in R?

How to import a CSV with a last empty column into R?

The real problem is that empty column doesn't have a header. If they had only had the extra comma at the end of the header line this probably wouldn't be as messy. But you can also do a bit of column shuffling with fill=TRUE. For example

dd <- read.table("~/../Downloads/jcr ecology 2020.csv", sep=",", 
   skip=2, fill=T, header=T, row.names=NULL)
names(dd)[-ncol(dd)] <- names(dd)[-1]
dd <- dd[,-ncol(dd)]

This reads in the data but puts the rows names in the data.frame and fills the last column with NA. Then you shift all the column names over to the left and drop the last column.

Importing csv files based on part of file name only in r

You can search files using a pattern:

q1 <- read.csv(list.files("your/path/", full.names = TRUE,
      pattern = "questionnaire1")[[1]])

can i use read_excel to import a csv file into r instead of using read.csv?

You can use read_csv (importing data as a tibble) or read.csv (importing data as a dataframe) for a csv file. Or you can save your CSV file as an excel file, then use read_excel.
