This is a rStudio question.
In the console, I put my first values in as:
x <- c(10.4, 5.6, 3.1, 6.4, 21.7)
and then I add my second values as:
y <- c(x, 0, x)
So why, when I enter in view(y), that is only show me 5 columns, but when I enter in length(y) is shows 11?
I don't understand. Please help?
Welcome to the forum.
Your results make sense.
x <- c(10.4, 5.6, 3.1, 6.4, 21.7)
length(x)
y <- c(x, 0, x)
length(y)
Therefore, 5 +1 + 5 = 11
Were you intending something like this?
z <- cbind(x, 0 , x)
length(z)
nrow(z)
If you type y
in the console you get
[1] 10.4 5.6 3.1 6.4 21.7 0.0 10.4 5.6 3.1 6.4 21.7
If you type View(y) (and note that V is a capital) you get however many numbers there is room for in the viewing window. If you change the width of the window you will see more or fewer.
No, I not trying to do anything like that. I guess I was asking how the viewing window works. It doesn't make sense that the view(y) only shows 5.
How can I change the width of the windows?
On my machine you can drag some little vertical lines in the View window to change how much is devoted to showing values or to change how large the window is.
I don't use View() but my guess is that you cannot without hacking the code.
View() is not intended to show all the vector, data.frame or whatever. It is intended to show the structure of your data.
This output is telling you that "Y" is a double-precision floating-point number vector with 11 entries, and is showing you a sample of the data.
You can get the basic equivalent using the base R command str()
str(y)
num [1:11] 10.4 5.6 3.1 6.4 21.7 0 10.4 5.6 3.1 6.4 ...
Further experimentation suggests I have no idea what View() is doing.
It acts like str() on a vector but is showing a rectangular "spreadsheet-like" output with no information about the variables.
Where I was expecting something like this
dd1 <- data.frame(AA = LETTERS[1:10], BB = 10:1, CC = as.factor(LETTERS[11:20]))
str(dd1)
'data.frame': 10 obs. of 3 variables:
$ AA: chr "A" "B" "C" "D" ...
$ BB: int 10 9 8 7 6 5 4 3 2 1
$ CC: Factor w/ 10 levels "K","L","M","N",..: 1 2 3 4 5 6 7 8 9 10
Interestingly enough
View()
# &
view()
are giving me identical results but this may be a function of the packages I have loaded. Ttere may be a view() in there somewhere.

View() with a capital V is built-in as part of the utils package. view() with a lower-case v is not part of base R so must come from some other package. The tibble package does have the lower-case version, but it seems to just call the upper-case version.
Ah, thanks. It was late when I wrote the above post and I decided bed sounded better than trying to track down View & view. It did strike me as strange though.
