similar to: Read data from .csv file as a matrix

Hello all, Probably my concepts about the data.frame and matrix and array in R are not clear, I need some clarification to help me understand them better. >M <- read.table("test1.csv",sep=",",row.names=NULL,header=T) gives me: M as M1 M2 M3 M4 M5 M6 M7 M8 M9 M10 1 9 11 14 15 18 20 20 20 20 20 2 3 4 8 9 11 12 14 15 15 15 3 4 5 8 8 9 9 9 9 9 9 4 4

Folks, I have a very basic question. The solution eludes me perhaps because of my own lack of creativity. I am not attaching a fully reproducible session because the issue may well be becuase of the way the data file is, and the data file is large (and I don't know whether I can legally distribute it). If people can suggest things that might be wrong in my data or the way that I am reading it,

I'm writing a program that will tell me whether I should wear a coat, so I'd like to be able to download daily weather forecasts and daily reports of recent past weather conditions. The NOAA has very promising tabular forecasts (http://forecast.weather.gov/MapClick.php?CityName=Ithaca&state=NY&site=BGM&textField1=42.4422&textField2=-76.5002&e=0&FcstType=digital),

I have a large Excel file with SKU numbers (stock keeping units) and forecasts which can be mimicked with the following: Period <- c(1, 2, 3, 1, 2, 3, 4, 1, 2) SKU <- c("A1","A1","A1","X4","X4","X4","X4","K2","K2") Forecast <- c(99, 103, 128, 63, 69, 72, 75, 207, 201) PeriodSKUForecast <-

Here is a funny story. We mostly do hotels in the Caribbean, and one of our first clients (going on ten years now) used the sample "weather.agi" that used to be shipped with... asterisk at home? Trixbox? Can't even recall where we originally got it from. This perl script uses festival to speak a brief weather forecast to the caller. We told our hotels this was a feature for

Couldn't find this in the archives. I'm fitting a series of historical weather-related data, but would like to use the latest values to forecast. So let's say that I'm using 1970-2000 to fit a model (using fourier terms and arima/auto.arima), but now would like to use the last X values to predict tomorrow's weather. I'm at a loss. All the functions I've come across

I installed it and it now gets current conditions just fine. but I tried several different locations

Ok, I've been away from the list for sometime now and feel as though I'm going to ask something that's been asked many times before, yet I find nothing in the wiki, so here goes: I notice that allison has done recordings for weather forecasts, yet I find no agi's that parse forecasts and use this recordings to piece together the forecast. I find plenty of weather agi's, but

I'm getting DNS not found errors from anything in NOAA.GOV. anyways, 'climate' refers to historical averages by location/month/week/date. presumably the API involved here was for current weather conditions

Hi all, I am dealing with very large numbers but I am only interested in their last digits. > 244^244 [1] Inf As far as I can tell, the largest number R can take has 308 digits (1+E308). Is there a way I could see the last digits only of 244^244? Many thanks for your help. Vincent Deluard, CFA. -- View this message in context:

All, I am toying with an idea of using an AGI to be able to 'call' my phone, or phones, in case of severe weather warnings. I have been tinkering with a script that reads from weather underground for the forecast, based off a PHP version of a weather AGI I found on the net. It seems rather trivial to have the AGI as a script, that does nothing unless a condition is met, and

All: I am using the command: qplot(date,MAE,data=data,facets=INTERVAL~type) which works fine except that the dates for my date axes are crunched together so much that they are unreadable. I can not find an option that I can set that will automatically reduce the x-axis labels to fit the available space. regards to all? -- Thomas E Adams National Weather Service Ohio River Forecast Center

Hi r users, I am trying to compute the "moving variance" of a large matrix. I now use a loop but I am looking for a faster solution. Here is a sample of the code. Source= matrix(rnorm(400),ncol=100) variances= matrix(rep(NA,4*100),ncol=100) for (i in 1:80) {variances[,i]=apply(Source[,i:(i+80)],1,var)} any idea? Many thanks in advance.

Does anyone know of a AGI script that takes advantage of the weather sound files that's included with the extra sound files available from www.loligo.com/asterisk/sounds/ <http://www.loligo.com/asterisk/sounds/> ?

I'm interested in creating a graphic -like- this: c <- ggplot(mtcars, aes(qsec, wt)) c + geom_point() + stat_smooth(fill="blue", colour="darkblue", size=2, alpha = 0.2) but I need to show 2 sets of bands (with different shading) using 5%, 25%, 75%, 95% limits that I specify and where the heavy blue line is the median. I don't understand how to do this with

Hi users. I'm new user in R. I'm workiing with Time series and I would like to know how can I do to undo the command DIFF(X), for exemple: If I have the model: m=arima(X, order=c(0,1,1), seasonal=list(order=c(0,0,1))) (note that have d=1 one difference), to find, in the same scale, the original numbers (like one "unDiff"), after the forecast, I need to develop some function or in
