search for: condition2

Hi All: Let's say I have two dataframes (Condition1 and Condition2); each being on the order of 12,000 and 16,000 rows; 1 column. The entries contain dates. I'd like to calculate, for each possible pair of dates (that is: Condition1[1:10,000] and Condition2[1:10,000], the number of days difference between the dates in the pair. The result should be a matrix...

I have a matrix with a lot of values inside.. when I execute the folowing command matrix2=subset(martix, condition.....) it works... but after the previous command I execute another "subset" matrix3=subset(martix2, condition2.....) and appears the following error: (subscript) logical subscript too long How can I solve this??? I think the probles is the size of the matrix... Thanks.. -- View this message in context: http://r.789695.n4.nabble.com/subset-in-a-BIG-matrix-tp3254115p3254115.html Sent from the R help maili...

...n, the main question is to test the effect of these parameters on the recorded results. When switching from Statview (old software on Mac computers, no longer supported) to R I learned that the problem is translated to a repeated measures ANOVA via ano <- aov(d$Result~ d$Condition1*d$Condition2 + Error(d$Subject/(d $Condition1*d$Condition2), data=d)) However, there are problems in performing post-hoc tests due to the intraindividual correlation of the repeated measures data. So I started intense online searches for a good solution in R, found snippets of R-code here and there. One p...

Hi all, I have a large dataset that has >10k entries. The dataset is stored in a dataframe with the headers: SubID Condition1 Condition2 Result1 Result2 There are multiple entries for a given SubID(Subject ID). Condition 1 has 3 levels and condition2 has 2 levels (therefore there are 6 possible combinations all together e.g. Cond1 Level1 x Cond2 Level 1 etc.) and i need to compute for 1. The mean for a subject of result1 and 2 for...

...ask an help because I have some difficulties in reading the output of that function.

Stimulus Condition1 Condition2 Condition 3 A 9 1 2 B 10 2 0 C 8 2 2 My goal is to prove that it is not by chance that Condition 1 is preferred rather than the other two conditions. So, I apply the function prop.test(), summing the values of C...

...entually hacked my way to an ugly solution for my particular problem but I would like to improve my coding: I have data of the form: df <- expand.grid(group=c('copper', 'zinc', 'aluminum', 'nickel'), condition1=c(1:4)) I would like to add a new data column "condition2", with values equal to the value of condition1 plus a random number from 0-1 (uniform distribution) if the value of condition1 is < 1, or just condition1 if the value of condition1 is > 1. More generally, my interest is in manipulating the values of condition1 if they meet one or more c...

...the following piece of C code: (incomplete and not compilable ;) ) result = initValue; for(i) { ... if(condition) result = updatedValue_i; ... } For targets with conditional moves, the result is updated using the following sequence of instructions: regTmp = regFalse; if(condition2) regTmp = regTrue; regResult = regTmp; Now, you have 2 cases: 1) either condition2 = condition In this case: regFalse is a phi node between the initial value of result and the current result. It's very likely that regFalse and regResult will be the same hardware register. So the sequence of in...

Hi everyone, I'm trying to create an "if" conditional statement with two conditions, whereby the statement is true when condition 1 AND condition 2 are met: code structure: if ?AND? (a[x,y] <condition1>, a[x,y] <condition2>) I've trawled through the help files, but I cannot find an example of the syntax for incorporating an AND in a conditional IF statement.

...4 1 7 2 028.175385 ... Here, one line equals the value of one subjects VARIABLE in function of the GROUP and the CONDITION. However, I would like to rearrange the data so that the columns of my data equal the 2 conditions and the lines the subjects. This is something like: subj group condition1 condition2 1 1 746.36625 46.36625 2 2 1076.152857 76.152857 ... I know its possible the other way around. But that's not what I need (this time). Before anyone asks: Yes, I want to do some analysis on my data in SPSS, so I need the rearranged format. Regards and Thanks, Dieter ------------------------...

I implement the following function,which gets CallInst * and should perform the following: 1. Change the value of the argument if condition1 takes place 2. Change the type of the argument if condition2 takes place 3. Add addition argument/s if condition3 takes place void argChange(CallInst * I) { for (unsigned index = 0; index < I->getNumOperands(); ++index) { do_something_with (I->getOperand(index),condition); } } I think that the 1. can be implemented using I->se...

Hello R-helpers, I'm writing a long function in which I manipulate a certain number of datasets. I want the arguments of said function to allow me to adapt the way I do this. Among other things, I want my function to have an argument which I will pass on to subset() somewhere inside my function. Here is a quick and simplified example with the iris dataset. myfunction<-function(table,
