Hello R folk
I have an xpt file which I have been trying to open into R in R studio
On the net I found guidance which says that I need packages Hmisc and SASxport

I had also found some code which says that this would allow me to read the xpt

Hello,
I am synthesising some sales data over a twelve month period, and then trying to

upper and lower 95% confidence limits. So far so good
But what I then want to do is add the upper sales value at the 95th
Hello This relates to trying to upload csv files to R. Essentially I have
some v large csv files, but in the column where the dates are appears the column

for example "01/04/09 00:00.0", and this never appears in

Hi R folk I have a distance time graph for a locomotive and at various times
different events occur on board the loco. I want to put a vertical line on the
speed time graph for each event, but I want to colour each different kind of
event differently to see visually whether there's any pattern
The first thing you need to do is to read your data in. Convert your excel file
to a csv file, say mydata.csv, and make sure that you know where it is eg folder
"Datafile" on C drive. Then use setwd("C:/Datafile") and then
read.csv("mydata.csv") That should upload it and you can trawl

Hi R Folk I have been kicking some data around and one thing has been to try a

1, I have 3, instead of 2 I have 4 etc etc. Despite ages playing around with
the axis function I can't get it to work, and
Hi Adrian I'm not sure that you need to use the ifelse here. You can simply
assign values ina vector or matrix using a simple condition -- here is a simple
example:
v<-c(4,5,6,7)
v1<-v
v1[]<-0
v1[v<5]<--1
v1[v>6]<-1

You probably have not reset the directory -- go to the session tab on the R
window, click and go to “set working directory” as C

Hi I am plotting various strands of information, and I want to create an

points no more than a fixed maximum distance from the plotted line, a bit like

You could try expand.grid -- you'd prob need to modify what's beneath

*b=c(0,1)*

*y[[2]]-b*

*expand.grid(y)*

Hello folks
Hello folks
Supposing I have a multidimensional array in an R prog, say a 4D array.
I want the coordinate quantities to be read off from a vector. The values
in the vector (vec) are generated by a function.
This is easy if the number of dimensions is fixed for both the array and
the number of
Something you could try is to put a small csv file into a location and set

eg

open this file, stick a csv doc and see whether R will read it
