long character string problem
Hi All
I am having 2 very long character strings (550chars) and I want to put them as
expressions together with c(). The problem is that I also get these
double-quotes, as seen below in 'fct'. How can I remove these double-quotes? I
tried as.name() but it did not work (because of size?). These are creating
trouble with subsequent programs, which I tested with strings that for some

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

Sink redundant spill after RA
Hi All,
I found some cases where a spill of a live range in a block is reloaded only
in one of its successors, and there is no reload in other paths through
other successors. Since the spill is reloaded only in a certain path, it
must be okay to sink such spill close to its reloads. In the AArch64 code
below, there is a spill(x2) in the entry, but this value is reloaded only
in %bb.1, not in

Manipulation of data.frame into an array
This is one of those instances where a less superficial knowledge of R's
technical details comes in really handy.
What you need to do is convert the data frame to a single (numeric) vector
for, e.g. a matrix() call. This can be easily done by noting that a data
frame is also a list and using do.call():
## imp is the data frame:
do.call(c,imp)
X11 X12 X13 X14 X15 X16 X17 X18 X19

Take the maximum of every 12 columns
Don't do this (sorry Thierry)! max() already does this -- see ?max

Take the maximum of every 12 columns
Thank you for your kind replies. Maybe I was not clear with my question (I
apologize) or I did not understand...
I would like to take the max for X0...X11 and X12...X24 in my dataset. When
I use pmax with the function byapply as in
byapply(df, 12, pmax)
I get back a list which I cannot convert to a dataframe. Am I missing
something? Thanks again!
Sincerely,

Take the maximum of every 12 columns
Dear all,
I have monthly data in wide format, I am only providing data (at the bottom
of the email) for the first 24 columns but I have 2880 columns in total.
I would like to take max of every 12 columns. I have taken the mean of
every 12 columns with the following code:

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,

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

Manipulation of data.frame into an array
Hello everyone,
Thank you for this. Nonetheless it is not exactly want i need.
I need mydata[[1]] to provide the values for all 3 variables (Y, X1 and X2) of the first imputation only. As it stands it returns the whole database.
Any ideas?
Best,
ioanna
