package or namespace load failed for ‘ks’

Hi?Friends?
	I have installed ks package successfully using R version 3.4.2 on Mac 10.12.6. But when I  library it ,  I have the following problem.

error: package or namespace load failed for ?ks?:
onLoad fails when'rgl'is calculated in loadNamespace ():
Call: dyn.load(file, DLLpath = DLLpath, ...)
Error: unable to load shared target object:?/Users/sanyu/Library/R/3.4/library/rgl/libs/rgl.so??:
dlopen(/Users/sanyu/Library/R/3.4/library/rgl/libs/rgl.so, 6): Library not loaded: /opt/X11/lib/libGLU.1.dylib
Referenced from: /Users/sanyu/Library/R/3.4/library/rgl/libs/rgl.so
Reason: image not found
	This is the first time I write emails to foreign friends , I hope I can get this helps.

The problem here is with the rgl package.  It requires that you have 
XQuartz installed.  That's not an R package, it's available from 
xquartz.org.

likely the separator character is not the default "," that csv expects.

look in the csv file and see what the separator character is: perhaps it is a ";" 

try:

df <- read.csv("example.csv", header=TRUE, sep=";"); names(df)

Hi,

Try this:

- attach(E)
- E$auto

In addition to which:

what does
   str(E)
show?

The file is small, so what do you get when you simply time
  E
at the R prompt?

header is TRUE by default in read.csv(), so it was unnecessary to supply header=T

read.csv2() has header=TRUE and sep=";" by default, so simply
    read.csv2('auto.csv')
should be sufficient if Tim's suggestion is the explanation.

read.csv() and friends are solid, reliable, and extremely well tested functions. If they don't succeed, you can assume that your data is different than expected. So inspect your data file to try and see what that might be.

Mac and Windows have different end-of-line conventions, but as far as I know read.csv and friends are smart enough to handle that.

Your locale setting might be relevant, but that's pretty much outside my experience.
