I would like to control the frequency of the X-axis labels, ticks and grid

before-after control-impact analysis with R
...from before-after
control-impact studies. J. Agric. Biol. Envir Stat., 5:262-279)
Data were collected from 1984, 1989, 1990, 1991, 1993, and 1996. Samples
from 1984 are considered as before an impact and the remaining years as
after the impact. Each year, 96 transects were sampled (36 in the
oiled area and 60 in the non-oiled area; "0" is for oiled and "1" for
non-oiled). The authors compare 3 different ways of analysing the data
including glmm. The data can be reproduced with the following commands
(density is fake numbers but I can provide the original data since I...

The "sealed cabinet", has enough expansion capacity for the oil to expand from heating;

Time series example in Koop
...Data". Koop does the example in Excel and I used the
ts function followed by the lm function.
I am unable to get the exact coefficients that Koop gives - my coefficients
are slightly different.
After loading the data file and attaching the frame, my code reads:
> y = ts(m.cap)
> x = ts(oil.price)
> d = ts.union(y,x,x1=lag(x,-1),x2=lag(x,-2),x3=lag(x,-3),x4=lag(x,-4))
> mod1 = lm(y~x+x1+x2+x3+x4, data=d)
> summary(mod1)
Koop gives an intercept of 92001.51, while the code above gives 91173.32.
The other coefficients are also slightly off.
This is the example in Table 8.3 of...

Reg: Frequency in declaring time series data
Dear All,
I have a time series daily data with date are stored ( %dd-%mm-%yy format )
from 22-01-20 to 03-08-21. In total I have 560 observations. I am using the
following command to declare as a time series object. Here the the data set
is 7 days a week.
oil <- read_xlsx("crudefinal.xlsx")
pricet=ts(oil$price, start = c(2020, 22), freq = 365)
roilt=ts(diff(log(oil$price))*100,start=c(2020,22), freq=365)
Shall I have to declare the dates here? I want to know also if it is a 5
day trading a week, how to declare the frequency.

Oil progress
The first thing to do in tuesday is to get in on EQTD. It will SOAR
up next week. There will be more than 100%

With oil markets retreating, big traders are turning to
gold, driving it to levels never before seen. EQTD has
made an advertisement of staggering proportions related to a
recent survey on one of their gold properties. The inside

Error on man page
Hi
I discovered a similar problem early this week and a colleage on irc was
told it was a copy and paste error.
in man syslogd, the following can be found:
Sucker rod def. -- 3/4, 7/8 or 1in. hardened steel rod,
male threaded on each end. Primary use in the oil industry in Western
North Dakota and other locations to pump 'suck' oil from oil wells.
Sec-
ondary uses are for the construction of cattle feed lots
and for dealing with the occasional recalcitrant or belligerent
individual.

Deformulation and R
...d to know if there is any R package which can help me
with a deformulation project.
Suppose e.g. that you know from a chemical analysis the fat, mineral,
vitamin, energy [and so on] content of a certain food product.
You also know the ingredients of this product (e.g. milk, lactose,
vegetable oil) and you know the chemical composition of each ingredient in
terms of fat, minerals, vitamins etc...
At this point the question, assuming that the procedure to create the
product from the ingredients does not alter the chemical composition of
any ingredient, is to determine the amount of each...
