I working with a csv that has 234 rows. I thought the length() function was supposed to return the number of rows in my csv, but it returns a much larger number. It gives me 1046860. Does the length function not do what I think it does? What is going on?
I just wanted to double check the length and haven't run any other code yet other than setting up my working directory and attaching a file (Cat6 <- read.csv("Category6.csv")).

I know that is really simple. I'm trying to calculate:
-2ˆ2 -(2.6)ˆ2 * (1/2)
Error: unexpected input in "-2�"
When I replace the ˆ with ^ it works on my system.

I am trying to replace parenthesis with "." in the string "abc(def)ghi".
The code used is following:
str_replace_all("abc(def)ghi", "\\)|\\)", ".")
The output is "abc(def.ghi".
.
The desire output should be "abc.def.ghi" .
Any easy way to achieve this in R?
You can use this snippet:
str_replace_all("abc(def)ghi", "[()]", ".")

I'm trying to do a simple calculation with my mean function. When I input mean(1, 10, 100), R returns 1, which is obviously not the correct average. It always returns the first entry of my vector. What went wrong?
You should use mean(c(1,10,100))
