Fellow beginner/ R noob brothers & sisters, if you see "No such file or directory", try changing the file name to just brUsers instead of brUsers.csv, it worked in my PC!
-
First time with R going through your videos. How do you all remember all these commands and stuff?
-
Couple notes
1. Excel files have multiple pages, but CSV files may only have 1
2. The CSV must be formatted such that only a header and columns of homogeneous values are present (he alluded to this already by saying it will be read as a data frame rather than generally as a list)
3. The data frame and CSV will not save formulaic data from an Excel file, but rather just the final numerical output of those formulae to each cell
4. Obviously, it also doesn't save any aesthetic changes to the cells or font, so a lot of data may be lost in this transfer if the original file is Excel
5. CSVs cells also are not able to refer to cells from other files; they're kind of dumb in general. -
Very nice …

first error: more columns than column names.
second error file not foind, i had in in my Documents. -
your tutorials are amazing!

In addition: Warning message:
In file(file, "rt") :
cannot open file 'br- Sheet1,True,': No such file or directory

Here's a linear regression of the CSV file that used in this tutorial:
————————————————————————
csvFile <- read.csv("D:/Projects_Programming/R/brUsers.csv",TRUE,",")plot(csvFile$age, csvFile$income, xlab = "Age", ylab = "Income")
ageMean <- mean(csvFile$age, na.rm = T)
ageMeanabline(v=ageMean)
model1 = lm(income~age, data=csvFile)abline(model1, col="red")
summary(model1)
—————Have fun———————————————-

Thanks a ton for these tutorials, you make learning programming simple and approachable 🙂

R did not grab the info, I followed your instructions (using a mac), the file was in my documents.
