read.table but more tables at once
Dear all,
I have a lot of data files (.txt) that I want to read in all at once, if
possible.
the files have names in time system. for example: RA940101, RA940102,
RA940103, RA940104 an so on.
(meaning: RA, year:91, month: here january, day of the month.)
I tried something like
vektor <- c("RA940101","RA940102","RA940103")
for (x in 1:3)
{ data <- read.table(paste(vektor[x],sep=""),header=F) }
But how can I put the vektor on the left side, so that data would be instead
of data the three first days of the year 1994?
best wishes and...

Comparing 2 slopes of 2 regression lines
Hello everyone,
I would like to test two regression slopes:do they differ significantly?The data and commands I've used so far:
x<-8.5:32.5 #Vektor x
y<-c( NA , NA , 5.67 , 6.53 , 6.83, 7.41 , 7.93 , 8.5 , 8.86, 9.46 , 9.82 , 10 ,10.35 , 10.7 ,11.03 ,11.37 ,11.61 ,11.84, 12.12, 12.39 ,12.67 ,12.96, 13.28 ,13.47, 13.65) #Vektor y
(regression<-lm(y~x))

correlation coefficient
Hello,
I would like to get a correlation coefficient (R-squared) for my model.
I don't know how to calculate it in R.
What I've done so far:
x<-8.5:32.5 #Vektor x
y<-c(NA ,5.88 , 6.95 , 7.2 , 7.66 , 8.02 , 8.44 , 9.06, 9.65, 10.22 ,
10.63 ,11.06, 11.37, 11.91 ,12.28, 12.69 ,13.07 , 13.5 , 13.3 ,14.14 , NA , NA , NA , NA , NA) #Vektor y
plot(y~x,col="green",pch=16,ylim=c(0,20),xlim=c(0,50))

Operations with long altrep vectors cause segfaults on Windows
I can only reproduce on Windows, but reliably (both 4.0.0 and 4.0.2):
$> R --vanilla
x <- c(0L, -2e9:2e9)
# > Segmentation fault
Tried to reproduce on Linux but the above worked as expected. Not an
issue merely with the length of the vector; for example, x <-
rep_len(1:10, 1e10) works, though the altrep vector must be long to
reproduce:
x <- c(0L, -1e9:1e9) #ok

Problem with a defined function which cannot access a function defined outside of the function
...is must be a
problem with
hidden parameters.
a workaround works when i just define all parameters instead of using the
function
itself. now the problem is that i want to integrate the function and i'm
not
sure how to do it with this workaround since i have a plot of the function
and
a big vektor with all points of the plot on the x-axis only.
Any help?
Thanks

It should be possible to do Chi-Square-Tests in a stratified analysis,
right?
