You loaded "lubridate" so using Erin's approach
library(lubridate)
st <- c("1961-01","1961-04","1983-02")
dat1 <- ymd(paste( st, "01", sep ="-"))

Please disregard I simply added a highlight variable and added
scale_fill_manual(values = c("Yes"="red", "No"="grey"))

While the following code works fine I need to change (highlight) specific
"bars" within plot 2 (p2). For example I want the bars to be (lets say)
red, on 1 Aug 2016 and 1 Aug 2017 . What do I need to do?
library(ggplot2)
library(reshape2)
library(scales)
library(egg)
Nice one!

Dear Paul,
Is it possible that you're overthinking this? That is, to you really need an R
model formula or just want to evaluate an arithmetic expression using the
columns of X?
If the latter, the following approach may work for you:
> evalFormula <- function(X, expr){
+ if
Can you point me at any packages that allow users to write a
formula with coefficients?
I want to write a data simulator that has a matrix X with lots
of columns, and then users can generate predictive models
by entering a formula that uses some of the variables, allowing
interactions, like
y ~

Another approach to adding GW_Elevation to the year value, but the table is
more compact with just the year.
dta <- read.csv("http://doylesdartden.com/R/ExampleData.csv;)
Years <- paste("GW_Elevation", dta$Year)
xtabs(GW_Elevation~Location+Years, dta)

Dear All: good morning
I am going to teach a course title "Introduction to Statistical Data
Mining", and I am using the book titled "*Introduction to Data Mining
(Second Edition)*" by Kumar and etal.
I am wondering if someone have R codes/functions for examples and exercises
given in this

Hi,
Which package/function do you recommend for Granger causality between x
and y with an error correction term?
In my problem, economic theory maintains that x~ I(1); y~I(1), x-y ~I(0)
\begin{eqnarray}
\Delta x_t = g_0 + \lambda_{x}(x_{t-1}-y_{t-1})+\sum_{k=1}^{n}g_{1k}\Delta
Hello,
I have a list of lists. The lists in the list of lists are file names. I
use lapply to read and merge the contents of each list in the list of lists
(3 merged contents in this case which will be the content of 3 files).
Then, I have to change the name of the 3 resulting files and
16 matches
