Dear R Experts that's my original equation > x=c(2,4) > Y1=sum(sapply(1:2,function(i){sum(sapply(1:i,function(j){(3^(x[i]+x[j]))}))})) > y1 [1] 7371 I want to write the inside function (3^(x[i]+x[j])) in a more condensed form cause this will help me when the multiple summations are more than two I've tried the following form > y2=sum(sapply(1:2,function(i){sum(sapply(1:i,function(j){(3^(sum(sapply(i:j,function(l){x[l]}))))}))})) > y2 [1] 819 But it didn't work, it gave another solution Any h...

Hi all, I need some help using read.ftable to read a contingency table. My columns are organized as follows: order--family--species--location--number of individuals I couldn't figure out how to change the data on my text file to be imported into R; and after you do that, is it possible to convert the table into a data frame? Any tips would be greatly appreciatted! Thanks a lot, Naiara.

...by filling zero values in for missing ys for the entire range of xs but in my case this would again create a vector too large for R. Is there another way to use the two vectors to create a simulated frequency histogram? Is there a way to create a histogram object (as returned by hist) from the condensed data so that plot would handle it correctly? Thanks in advance, Jesse

Hi, When a call is made to a queue and picked up by agents at least 2 CDR entries are made, one from local to the agent's (sip) phone, and from incoming line to Agent. There are other entries generated when other conditions happen, like agent do not pickup phones and so on. Going through the cdr entries, there seems to be no common filelds by which all entries belonging to a single call can

Hello all, I'm currently using R to do PCA Analysis, and was wondering if anyone knew the specific R Code that could limit the output of the PCA Analysis so that you only get the Principal Component features as your output and none of the extraneous words or numbers that you don't want. If that was unclear, let me use linear regression as an example: "lm(y~x)" is the normal

I have used R for years but run into a seemingly simple problem involving 'ifelse'. condensed code like this a=c(2,NA,NA,NA,2,2,NA,2,NA,2) b=c(NA,1,1,NA,2,2,2,2,2,2) #I want to combined a and b into c so that c would be a valid number either a or b is not missing c=ifelse(a==1|b==1,1,ifelse(a==2|b==2,2,NA)) cbind(a,b,c) a b c [1,] 2 NA NA [2,] NA 1 1 [3,] NA 1 1...

Hi, I would like to plot a linear relationship between variable x and y. Can anyone help me with scaled plotting and axes so that all data points can be visualized somehow evenly? Plaint plot(x,y) will generate condensed points near (0,0) due to several large data points. Thank you.

...ight hand to signal the switchboard. The two dry cells inside are dated 1935, and I'm throwing them away because they're leaking acid. Wouldn't it be a kick to be able to ring this phone from an * server and have a conversation. There are several lugs inside: L1, GND, L2, COND (no condenser installed), E, and K. And of course the two battery lugs. Does anyone know anything at all about this set? I realize the CO supplies battery instead of the telephone, but can the phone be modified? Also, am I going to blow a FXS card if I don't get it right? Cheers, Mike

I have applied the same linear model to several different subsets of a dataset. I recently read that in R, code should never be repeated. I feel my code as it currently stands has a lot of repetition, which could be condensed into fewer lines. I will use the mtcars dataset to replicate what I have done. My question is: how can I use fewer lines of code (for example using a for loop, a function or plyr) to achieve the same output as below? data(mtcars) # Apply the same model to the dataset but choosing different com...

Dear all, Possibly a rudimentary question, however any help is greatly appreciated. I am sorting a large matrix into an array of dim(p(i),q,3). I put each entry into a corresponding matrix (1 of the 3) based on some criteria. I figure this will assist me in condensing code as I can loop through the 3rd dimension of the array instead of generating 3 separate matrices and using the same block of

I've been able to view the results in R, but I want to get the results out to a database and a matrix that is 6000-rows x 6000-columns can be very difficult to manipulate in Windows XP. I would to rotate the matrix so that the output would look like the old condensed format in programs like Conoco. Ideally, I would like format to look something like this; Site-row Site-col Jaccard 1 1 1 1 2 .9 1 3 .6 2 1 .9 2 2 1 2 3 .75 Thanks for any help, *********************************************************** John...

...e are multiple rows corresponding to the same variable level (e.g., "temperature=8, 5 observations" in one row, then the next: "temperature=8, 9 observations", and so on). In other words, the data are not one long vector R can read and plot as a histogram, nor are they condensed. My goal is to create a figure in which one axis is bins (e.g., temperature values) and the other is number of observations in this bin (e.g., number of organisms seen). My question is: Is there a way R can be told to read my data to create a plot like that I desire? So far I have tried s...

I then want to condense the unique values by summing the CONVUNIT for each unique value of TRIPID. I posted a similar question last week and received a sufficient answer of how to do this without using uniqe. The solution below worked just fine on this sample data set but the full data set has 446,000 rows of data and m...

Hello, I was wondering if there was a method in Rails that returns the sum of a column. For example, I have a column called ''score'' and writing a SQL statement such a ''select sum(score) from table_name'' does return the sum of the values in the column. In the past (not too long ago being a newbie), I defined all sorts of methods only to discover that Rails

...rigger an error message for you, because it tries to do things that are specific to my machines. The not-OK one says "skipping .First", as below, and you'll see why it shouldn't be doing that. Obvioulsy, the files need renaming before you can test them. I haven't been able to condense the .First to something more succinct that shows the same fault; saving a modified .First frequently makes the problem go away, seemingly regardless of what the change is.
