@ahmed007Jaber
interesting! thank you for the alert!. if u have categorical data that you then coded them with numbers. would u convert them into factors or (charachter> numeric)?

@da_ta
You make great videos unfortunately the sound is not good enough some videos you made perviously have echoes. This one low sound. I hope you will fix this. Keep up the hard work.

Joachim, Thanks for another great video.
I was fiddling with a messy dataframe that had a lot of variables in the wrong format - lots of numeric cols in char format and I thought drat this will take some time to convert but then I ran across a package called "hablar". It is based on dplyr (hence the pipe works) so perhaps another addition to the tidyverse. Long story short. This package has a function called "convert()" that can change a lot of variables in single line of code - for instance to change the following columns to char, int and dbl:
convert(chr(x, y, z), int(w, t, q), dbl(s, r, p)) - just amazingly simple. I think it even accepts : or
a:d or a continuous range of columns. Check it out.

@borknagarpopinga4089
Hello, sometimes I get the following error message: 'list' object cannot be coerced to type 'double'...what does that mean? I have a data set/dataframe full with numeric variables, but after replacing missing values with the median of each column, the type of the columns changes from numeric to character. Now I want to change it back to numeric, but get this weird error message. What can I do? Additional info: The last column is a binary outcome (0 and 1) which obviously has to be a factor, if I want it to use Logistic Regression etc.

@SanaKhan-wl6bf
x_fac_to_num<- levels(x_fac_to_num)[x_fac_to_num]
x_fac_to_num <- as.numeric(x_fac_to_num)

Would this work too? first, we can index the levels of x_fac_to_num which produces a character output of the actual contents of the input vector for which we can then convert that to numeric using as.numeric function...is it the same thing ? What's the difference? Also, why does using the vector to index factor levels produce the correct output of the vector instead of the levels?
