I am new to R, so bear with me if my question is trivial. I ran a system of
simultaneous equations with panel data and using the systemfit program, but the
results came out by country. I want the results for the entire panel and not by
country. What command will I use? Thanks!

When you have cooled down you may notice that the answer to your question was
in items a-d, though Bill's use of str made it clearer. Also, there was in fact
no call to yules.k1, much less one that includes sample data. You will find
that the solution to problems in R are very often related to t
Thank you Ista and Duncan for the swift replies.

for information about those date format specifications ( "%V" for example),
and an introduction to R's handling of date and date-time values.
And a few quick examples, to see that %V works as advertised:

In addition to which, the original question uses an incorrect way to reference
columns in the data frame.
It should probably have been:
newMyData <-MyData[!is.na(MyData$col1) | !is.na(MyData$col2) |
!is.na(MyData$col3) |
!is.na(MyData$col4) | !is.na(MyData$col5) , ]

I do think I have managed to tell Rcurl to ignore cert errors with the addition
of the .opts = list(ssl.verifypeer = FALSE) line in the "postForm()" call.

Regarding the question:
From the linux shell I use the "-k" switch with cURL to ignore cert
errors.. is there an equivalent in the R world?
I have (sometimes) had success by creating a .curlrc file and putting the
necessary curl options in it. When R invokes curl, curl picks up the options

Printing a number does not show whether it is stored
as a 32-bit integer or as a 64-bit floating point value.
Use. e.g., str() or class() to see.

Your snapshot did not make it to the list. Only a few types of plots are
accepted, e.g. .png. But we don't need a picture as much as we need a copy of
your code with enough of your data to reproduce what you are trying to do. Use
dput(head(x, 15)) to print out 15 lines of your data and include a
Hi Luís,
The parallel package is built-in, and so is not distributed via cran.
You'll see the same thing for all the built in packages, e.g.,

Hi Shakeel,
Assuming that you are starting with a bunch of dates:
# make a vector of character strings that can be converted to dates
rep_dates<-paste(sample(1:30,500,TRUE),sample(1:12,500,TRUE),
sample(2013:2017,500,TRUE),sep="/")
# if this isn't your format, change it
date_format<-"%d/%m/%Y"

Hi Shakeel,
One approach would be to look at the dplyr package and its functions
group_by() and summarise(). These should be useful in preparing the data.
(Alternatively if you know SQL you might look at dbplyr.)
On the plotting side you can use plot(...) for the first line and then
lines(...) for

I am fairly new to 'R' and would like advice on the following. I want to

a) Numeric values may be either integers (signed 32 bit) or double precision
(53 bit mantissa).
b) Double precision constants are numeric with no decoration (e.g. 61224).
Integer constants have an L (e.g. 61224L).
c) 61224*61224 > 2^31-1 so that answer cannot fit into an integer.
