How can I have both printout and saved results at the same time.
The subroutine first return "out" and the printout gets printed, but not
saved.
I then run the "invisible" line. Results got saved and accessible but no
printout.
How can I have both printout and also have the results saved?
Thanks to all. Great ideas. I found Eik Vettorazzi's suggesstion easy to
implrment:
ebarm<-vbarm<-NULL
...
if (is.null(ebarm)) ebarm<-ame.00$ei/k else ebarm<-ebarm+ame.00$ei/k
if (is.null(vbarm)) vbarm<-ame.00$vi/k else vbarm<-vbarm+ame.00$vi/k

but now with R3.6 I cannot replicate the results.
Below I sample 60 observations from 1:500 using the sample command with
a random seed of 123. I get different results. Advice appreciated.

Great! Thanks.

Dear All,
I would like to get a matrix (table) printed in a procedure, as
attempted below. Please help. Thanks.
test<-function(x){
table<-matrix(x,nrow=4)
cat("\nTable:\n",table)
invisible(list(table=table))
}
x<-1:20
test(x)

I like to print a vector, wrapped by rows of 10.
Below the first command below works for 20 numbers.
The second command is ugly. How can I print the 25 numbers into 2 rows
of ten plus a helf row of 5? Thanks.

[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8]
I install package using either the command line or Tools -> Install
packages... (in RStudio) and get a non-fatal message saying...
Installing package into ‘C:/Users/xuhaer/Documents/R/win-library/3.5’
(as ‘lib’ is unspecified)
I know it is not a fatal message. But, is there a way to do a cleaner
a base function try() so that's not a great

I would like to suppressed printing of retrievable results in a
procedure and to print only when retrieved.
In line 10 below I call procedure "try" and get matrices A,B,C all
printed upon a call to the procedure. I get around this unwanted
printing by calling with v<-try(A,B) as in line 11.
I have known from the old days to set a random seed of a LARGE ODD
NUMBER. Now I read instructions of set.seed and it requires ANY INTEGER.
Any idea? Or, does it matter. Thanks.

How do I print a matrix running a procedure? In the code below, I print
with the cat command and get a vector (from A and C).
A<-matrix(rpois(16,lambda=5),nrow=4,byrow=T)
B<-diag(4)
try5<-function(A,B){
C<-A+B
cat("\nA =",A,"\nC = ",C)
structure(list(A=A,B=B,C=C))
}
v<-try5(A,B)
v$C

I need help with "apply". Below, I have no problem getting the column sums.
1. How do I get the sum of squares?
2. In general, where do I look up these functions?
Thanks.
x<-matrix(1:10,nrow=5); x
sum <- apply(x,2,sum); sum

David, Rui, and All:
Greetings.
1. I need a helping hand with the polygon statement below so that I can
have the area under the curve highlighted, between (z1,z2).
2. Is it possible to label the X-axis with in two scale, in the current
z-scale and another, say x = (z+5)*2?
Thank you.
z1<- -1
Is it possible to release the file destination after sending it to a pdf
file?
Below, line 3 send the graph to a pdf file.
I like to release the devise so that I can see result produced by line
for on the console (screen). Thanks.
x<-1:10
pdf("test1.pdf") # pdf {grDevices}
boxplot(x) # This
Thanks!!! It did wonders.

Can someone help me with polygon. The following codes are self-runnable
and mark a shaded area under the standard normal curve in the x-range
(-3,-1).
Is there a way to also mark the area in (1,3), at the same time.
That is, I want shaded areas in both tails. Thank you...

# Create data for
I am trying to build an R package with Rtools version 3.5.0.4 along with
R-3.5.1
using the following sequence of commands:
File -> Open Project -> Build -> Build Binary Package
I received the following error message:
zip I/O error: No such file or directory
zip error: Temporary file failure
I have had trouble installing packages (e.g., car, aod) in some
computers (such as computers in the student lab) but no problem in my
own laptop.
Installation typically goes through, but after I got out and back in R
(and RStudios), the error message says "packages xxx not available".
That is,
I build binary data files into a library by placing the .rda files at the
proper \data sub-folder before building the library with the following
procedure:
1. File -> Open project
2. Build -> Build binary packages.
This has worked up to 3 .rda files.
Now, I add another .rda file to the folder.
I have trouble documenting an R package. In my .Rd file (sixth line below), I
have
uhat<-m%*%y
but when the package is built (successfully), the matrix multiplication part
does not show up in the documentation. The line become (missing %*% y)
uhat<-m

I am running R-3.0.3 on RStudio 1.1.183. I have recently gotten the following
error message while saving an .RData file with the save.image command. I have
not had this problem until recently. Help appreciated.
===
Error in save.image("bope1a.RData") :
image could not be renamed and is left
Understood. In my case, a.RData and b.RData contain identical
variables/data, plus simulation outputs from separate runs. The codes
deliver what I need. Good to know the three lines work. Thank you.
