Something like:
d = data.frame(score = sample(1:10, 100, replace=TRUE))
d$score_t = "low"
d$score_t[d$score > 3] = "medium"
d$score_t[d$score >7 ] = "high"
d$score_t = factor(d$score_t, levels = c("low", "medium", "high"),
ordered=TRUE) #set ordered = FALSE for dummy variables
X = model.matrix(
Thanks you all for the assistance. This really helps.
Hi Bert: While searching nabble i got to know R with factors variables
there is no need to create dummy variable. However please consider this
situation:
I am in the process of building a logistic regression model on NPS data.

What's wrong with this?
df$Night <- as.POSIXct( paste(format(df$Date,'%Y-%m-%d'),'21:30'))
or
df$Night <- trunc(df$Date,'day') + 21*60*60 + 30*60
I believe both of those satisfy "the day of tracking for each animal, but
with the time of 21:30". But perhaps you meant the day that tracking

Just commenting on the email subject, not the content (which you have
already been helped with): there is no need to *ever* create a dummy
variable for regression in R if what you mean by this is what is
conventionally meant. R will create the model matrix with appropriate
"dummy variables" for fac
Hello,
Your ifelse will never work because
reasons$salutation== "Mr" & reasons$salutation=="Father" is always FALSE
and so is reasons$salutation=="Mrs" & reasons$salutation=="Miss".
Try instead | (or), not & (and).
Hope this helps,

Hello,
I'm using the function gammamixEM from the package mixtools. How can I return
the graphical output of density as in the function normalmixEM (i.e., the
second plot in plot(x, density=TRUE)) ?
Thank you very much for your time.
Have a nice day.
