To the R experts,
I am currently playing with a program which was designed so that the outputs
are to be read in Surfer. I do not have the program, but the files, can
but put into excel and graphed. I figured i could do the same thing with R.
If I open the file with excel, and put the text into
The problem is, if I use read.table I get Error in
read.table(HeatLow_maphhs000.1994010101) :
duplicate 'row.names' are not allowed
if I try table-read.table(HeatLow_maphhs000.1994010101,sep= )
Then I get:
Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings,
:
Surprisingly in this case, the simplest solution was the best one. Using
read.table(filename,skip=4) was all it took. Cheers :)

Ok, took me a while, but I figured it out. Because my running mean had less
years than my standard rainfall graph, when I overlaid the running mean onto
the rainfall it was trying to stretch out. So I just plotted both onto the
same graph., like so:
barplot(Ann,main=title,
Thanks guys. I ended up doing as you suggested Dieter. Thanks for the idea :)

Thanks for the help guys. This worked:
x-sqlQuery(conn, select to_char(lsd,'-mm') as yr,ttl_mo_prcp from
mo_rains where stn_num=23090)
myDF=x
myDF[,1]=as.yearmon(myDF[,1])
myDF$R=myDF$TTL_MO_PRCP
myDF[,-2]
myDF$-substr(myDF$YR,5,8)
myDF$mm-substr(myDF$YR,1,4)
myDF-subset(myDF,
Thanks Greg, the problem is I have no idea how to return and use what I have
typed into the pop up. Add to that the complication that with this query
x-sqlQuery(conn, select to_char(lsd,'-mm') as yr,ttl_mo_prcp from
mo_rains where stn_num=23090)
if I put anything other than a number into
This is the very last thing I need to make everything work properly. My
query:
sqlQuery(conn, select to_char(lsd,'-mm') as yr,ttl_mo_prcp from
mo_rains where stn_num=023000)
Is there a way to may the stn_num in the query variable, ie make it so that
whenever my script is run, the user must
Thanks mate, awesome :)
Everything is now working as ordered. Thanks to everyone who has chipped in
and helped out this past week, much appreciated!!!

I have written in R this:
require(tcltk)
tt-tktoplevel()
Name - tclVar()
entry.Name -tkentry(tt,width=20,textvariable=Name)
tkgrid(tklabel(tt,text=Please enter site number.))
tkgrid(entry.Name)
OnOK - function()
{
NameVal - tclvalue(Name)
use.this=NameVal
tkdestroy(tt)
}
Dear anyone who knows more about R than me (so everyone). I have been bashing
my head on the keyboard all day trying to do something with my table.
I have some data, like so:
-mm Rainfall(mm)
1 1977-0217.4
2 1977-0334.0
3 1977-0426.2
4 1977-05
the other alternative would be to edit my sql query so that that data is
brought in from the database and put in to the correct format initially.
sqlQuery(conn, select lsd,ttl_mo_prcp from mo_rains where stn_num=23090)
That is my very basic query. I have also been given this for use in orcale
Cheers Jim.
However when I input:
axis.ticks-seq(kent[1,2],kent[dimkent[34,2]],by=10)
I get the error Error in dimkent[1,2] : incorrect number of dimensions
What are these dimensions that I am meant to have in there? I have tried
total dimensions of the table, dimension of the row that I
ok, used the lapply function and now the Years column is the numeric type.
However, I still get the same error as above. Replacing either kent[1,1]
or kent[dimkent[1],1] with a number, gives me the same error. If both
terms are replaced with a number, then it does not produce an error. It then
To everyone else, it is going to look like I am talking to myself.
Jim, I got your reply (to my post which I changed almost as soon as I posted
it), and as.numeric(as.character(kent$Year)) is a god send. Worked a
charm, and fixed all the problems. So thanks :)
Last issue now (at least for this
This worked:
dimkent-dim(kent)
axis.ticks-seq(kent[1,1],kent[dimkent[1],1],by=10)
barplot(Ann,main=title, xlab=Year,ylab=Rainfall (mm),
ylim=c(0,ymax),col=blue,space=0)
axis(1,at=seq(1,rows,10),tcl=-0.5,labels=axis.ticks)
Thanks Jim! You just saved my life.

ok, solved it. Hoowever (there is always a however), I would like to centre
the line plot of the rolling mean onto the centre of each bar in my bar
plot. Currently, the lines aligns itself with the RHS of bars.
I have tried this
Thanks mate, will get the zoo package ASAP. I have been working on the file
open/save part, and it works as planned except for one bit. When I save it,
it does not save as the relevant file type.
This is again my code:
require(tcltk)
fileName-tclvalue(tkgetSaveFile(filetypes={{PNG Files}
Now, I think I am making this harder than it seems, but...
I am writing a script that will allow me to pull any csv file with annual
rainfall and plot it into a bar plot. The problem I am facing is that the
different sites have recorded data for a different number of years. This
means that every
Thanks Jim, however if I change png(fileName) to png(picture.png) then
this:
require(tcltk)
fileName-tclvalue(tkgetSaveFile(filetypes={{PNG Files} {.png}} ))
becomes obsolete. Assuming of course that is what you were referring to.
Otherwise I completely missed your point.
Cheers.

G'day, I am new user to R, and have been thrown in the deep end with a
something my company want me to write.
my code is as follows:
kenttemp=read.csv(mnowak.11.1.csv)
rows=nrow(kenttemp)-5
kent=kenttemp[1:rows,] #have to remove the last 5 lines of the
graph as they interfere with
21 matches
