Just to clarify,
if you have two data.frame, one with your data, other with data-admissions,
just use
data.merge<-merge(my.df, data.weigth, by.x="data", by.y="data", all=T)

Hi Rob Williams
I think it is one way of you do the job.

my.df<-data.frame(cbind(data=sample(c("mon","sat","sun"), 20, replace=T),
values=rnorm(20)))
my.df$values<-as.numeric(my.df$values)
data.weigth<-read.table(stdin(), head=T, sep=",")

code much appreciated.

Subject: Re: [R] Using if, else statements
You might have found 'ifelse' in S Poetry, which
is one way of solving your problem.
One more try and I quit: This is what happens if someone does not
sent a sample of data you have to create things on the fly without
testing.
days <- list(list("Sat", 1.21), list("Sun", 1.22), list("Mon", 0.91))
for (i in days){
.subset <- data$d.o.w == i[[1]] # subset of data that matches
My fingers slipped on the keyboard. Here what they intended to write.
This sets up a list of the data and the matches on a subset for
processing
days <- list(list("Sat", 1.21), list("Sun", 1.22), list("Mon", 0.91))
for (i in days){
.subset <- data$d.o.w == i[[1]] # subset of data that matc
You would have something that looks like this:
if (data$d.o.w == "Sat") data$admission <- round(data$admission * 1.21)
if (data$d.o.w == "Sun") ...

Hi all,
Again I have searched the net and so on, without finding an answer to this
surely simple problem. A short bit of code would be appreciated.
I have a object named `data' with the following column headings.
Date, maxitemp, minitemp, admissions, d.o.w.
Where d.o.w. is day of the week,
8 matches
