truncation/rounding bug with write.csv
To my surprise, I can confirm on Windows 10 using R 3.4.3 . As tail is not
recognized by Windows cmd, I replaced with:
system('powershell -nologo "& "Get-Content -Path temp.csv -Tail 1')
The last line shows only 7 digits after the decimal, whereas the first have
15 digits after the decimal. I agree with Dirk though, 1.6Gb csv files are
not the best way to work with

Accessing examplars in apcluster (apcluster package)
Hi,
I was wondering how it was possible to access the actual cluster exemplars
from the APResult class. Currently it only spits it out onto the terminal
if you type the object but there is no other way to see which one is the
examplar.
Would appreciate any help.
Thanks,
Sachin

a Question regarding glm for linear regression
Hello All,
I have a question about glm in R. I would like to fit a model with glm function, I have a vector y (size n) which is my response variable and I have matrix X which is by size (n*f) where f is the number of features or columns. I have about 80 features, and when I fit a model using the following formula,?
glmfit = glm(y ~ x1 + x2 + x3 + x4 + x5 + x6 + x7 + x8 + x9 + x10 + x11 + x12 + x13

change the height or scale of the y axis
Hallo, All,
I have a question about changing the height or scale of the y axis. When I
use following two R codes, I can get two plots. Please look at the y axes,
the number of indices (x1, x2, ?) on the y axis in the first plot is smaller
than that in the second plot, and hence the space between any two indices in
the first plot is wider than that in the second plot. As the number of
indices

as.character limits length of result for formula
If you want a character representation of a long formula (or
a formula with long names), you can use:
as.character(my.formula)
However restriction on length of an as.character result
returns only the beginning of a long formula, and without comment.
In most cases, the following expression provides the complete
result:
paste(my.formula[[2]], " ~ ",

Query about creating time sequences
Hi All,
I have a query about time based sequences. I know such questions have been
asked a lot on forums, but I couldnt find the exact thing that I was
looking for.
I want to create a time-based sequence which will mimic the trading window
AND would span multiple days. Something like below:
"2011-01-03 09:15:00 IST"
"2011-01-03 09:15:01 IST"

calling data frames
Dear List,
I've around 1000 *.txt files, I've generate with other software.
I've now done the following code (below).
My question is how can I automate this (with do.call () ?), so it could be
done for all the *.txt files.
Thanks in advance,

RV: LATENCY PROBLEMS
Hello there,
I''m having lots of problems with my setup here. Let me explain:
I am network administrator for my university dorm. We are about 300 users,
and we have 2 ADSL connections doing load balancing with 300kbits upstream
and 2Mbit downstream.
The load balancing is working great, we are doing connection tracking so I
can mark and hence prioritize interactive traffic and ACKS

truncation/rounding bug with write.csv
What OS are you on? On Ubuntu 17.10 with R 3.4.3 all seems well (see
below for your example, I just added a setwd()).
[ That said, I long held a (apparently minority) view that csv is for all
intends and purposes a less-than-ideal format. If you have that much data,
you do generally not want to serialize it back and forth as that is slow, and
may drop precision. The rds format is great for R

truncation/rounding bug with write.csv
My apologies for not including sessionInfo(), and I'm a bit angry at myself
for that. Retrying in a fresh session of R, I get different results. More
specifically, I get the expected result where accuracy is the same in the
first and the last line. As I didn't include my sessionInfo() in my
previous mail, I can't figure out why I now have a different result. So I'm
positive

basehaz() in package 'Survival' and warnings() with coxph
Hello,
I have a couple of questions with regards to fitting a coxph model to a data
set in R:
I have a very large dataset and wanted to get the baseline hazard using the
basehaz() function in the package : 'survival'.
If I use all the covariates then the output from basehaz(fit), where fit is
a model fit using coxph(), gives 507 unique values for the time and the
corresponding cumulative

I've never seen this, and have no idea how to reproduce it.
For resloution you are going to have to give me a working example of the
failure.
Also, per the posting guide, what is your sessionInfo()?

Reading JPEG file, converting to HEX
Colleagues,
I am using R to assemble RTF documents (which are plain text). I need to embed a JPEG graphic that was created with R. I presume that the steps need to be:
a. read the file into R
b. convert the object to HEX format
c. write the converted object to a textfile.
If I read the file into R using readLines, I get the following (only the first 5 lines shown):
