Hi All,
Sorry about this quite basic, but I am very new to R.
I have a data file which has a dependent variable (reaction time) and a couple
of independent variables, one of which is coded 1-8; I want to calculate the
reaction time for each of the 8 codes of the independent variable.
Thanks
Hi Laura,
I think you're looking for aggregate()
See ?aggregate
If you had posted a reproducible example, I could have given you a more
detailed answer. Learn to use the dput() function to do so.
If you're very new to R, maybe this could help you get started:
Hello,
Like Ivan said, you should give us a data example, the best way is to do

#1 1 1 1 674.8947

Hello Dear R-help Members,
I have noticed that when pasting text with tab in it to the R console it
eliminates the tab. Whereas, when pasted into the R Editor, the tab is
preserved.
For example, pasting this:
1997 7680
In the R Console will result in:
19977680
Is there a way to preserve the tab?
Pasting tabs into the console works for me on linux, which suggests
that you need to provide more information about your OS and all the
other usual things.

I have come across this issue many times. I have yet to find a pattern in what

At least I can offer a workaround. Instead of using Save As to create the

It is helpful if you provide a simplified version of your question with
data. For example:
# simplified example
y - c(2.2, 2.4, 2.35, 2.45)
upper - 0.17
lower - upper
# current plot, with default base of 0
b - barplot(y, ylim=c(2, 3))
arrows(b, y+upper, b, y-lower, angle=90, code=3)
Nico,
It is unclear to me what sort of result you are looking for.
Can you give an example of what the output would look like using the
example data you provided?
You can look at the occurrence of names and places using the table()
function,
table(a$name, a$place)
or you could look at the
Hi,
It is not clear.
dta1-do.call(data.frame,dta)
dta2-dta1[complete.cases(dta1),]
dta2[,-3]-lapply(dta2[,-3],as.character)
lstdta2-split(dta2,dta2$place)
library(plyr)
join_all(lapply(lstdta2,`[`,-1),by=name,type=inner) #none of them are common
#[1] name value value value value value
#0 rows
It may be easier if you convert the list you provided to a
data.frame:
dta.df - data.frame(place=dta$place, name=dta$name,
value=dta$value)
dta.df
Note that the last line is blank so you probably want to remove that
and remove the blank factor levels:

Hi All, whenever I open R using the shortcut on desktop, there are 2 active

It sounds like you inadvertently saved a workspace file. Have a look in your
current directory and see if there is an .RDATA file there that you don't
recognize. If so, delete it.
