Does anyone know of a simple test in any R package that given a series of negative ones and positive ones ( no other values are possible in the series ) returns a test of whether the series is random or not. ( a test at each point would be good but I can use the apply function to implement that ) ? thanks.

I'm sorry to bother this list so much But I haven't programmed in A while and I'm struggling. I have a vector in R of 1's and -1's And I want to use a streak of size Y To predict that the same value will Be next. So, suppose Y = 3. Then, if there is a streak of three ones in a row, then I will predict that the next value is a 1. But, if there is a streak of 3 -1's in a row, then I will predict that a...

Suppose I have the first vector: c(1, 6, 8, 9) I will like to create a second vector of size 10 composed of 0 and 1's. The second vector will be composed of four 1's and six 0's. The position of the 1's will be specificed by the first vector. So essentially, I want a second vector in the form: c(1, 0, 0, 0, 0, 1, 0,...

Hi all, Here's an interesting (for me, at least!) problem I came across: I have a correlation matrix, let's say with 6 variables, A to F, as column headings and the same 6 as row headings. The matrix is filled with correlation coefficients. Therefore, the diagonal is all 1's, and each of the two triangles formed by the diagonal has the same 15 correlation coefficients. I need to extract these 15 coefficients from this. I don't want the 1's and I don't want redundant values. I tried converting the matrix to a list, using c(m) and then I'm stuck. Do...

Dear R-users, I have some very simple data where 1's represent events and zeroes non-events, e.g. temp <- rbind(c(0,1,0,0,1,1,1,0), c(0,0,0,1,0,0,0,0)) For each row in the matrix, I would like to replace a singelton event by a 0. That is, any 1 surrounded by zeroes (010) should be replaced by a zero (000). Sequences of 1's should be lef...

Hi All, We have a raw dataset that, on the sampling time column, for example: t <- c(0,1,2,5,0,5,0,2,5) And we need to create a second column that indicates the day of the sampling, so the end result of what we want is a vector: 1,1,1,1,2,2,3,3,3 Additional information that might simplify the matter is that, for each day, the time starts with zero and ends with 5. I am a beginner with...

Full_Name: S?ren Faurby Version: 2.4.1 and 2.7.2 OS: Submission from: (NULL) (192.38.46.92) There appear to be a bug in the estimation of significance in the binomial model in GLM. This bug apparently appears when the correlation between two variables is to strong. Such as this dummy example c(0,0,0,0,0,1,1,1,1,1)->a a->b m1&l...

I have a binary matrix of size N x 300. I then create the following: > set.seed(1234) > (key_file <- sample(letters[1:4], 300, replace=TRUE)) [1] "a" "c" "c" "c" "d" "c" "a" "a" "c" "c" "c" "c" "b" "d" "b" "d" &qu...

Hello everyone, If I have an incidence matrix of 0 and 1's P=[1 1 1 1 1 1 1 1 1 1 0 0 1 1 1 0 0 0 1 1 1 0 0 0 1 1 0 0 0 0] I want to create a new uniform random matrix [a] that is filled with 0's and 1's but constrained so that the row and column sums are the same as in [P]. Does anyone know how to accomplish this? Thanks in...

...s on two floors. They have an agreement between them whereby they'll answer each other's incoming calls and take messages if the office is empty / everyone is on the phone. Each of them has an ISDN BRI delivered to asterisk via zaphfc, then dropped into a context as follows: exten => s,1,SetCIDName(Company 1) exten => s,2,Dial(SIP/200&SIP/201&etc.,30) exten => s,3,Voicemail(su200) Each company is able to see on the LCD on their SIP phones whether the call is for them or the folks up/downstairs. What I'd like to do is implement a delayed ringing strategy - i.e. i...

...ath set to false and using an unordered compare. Could someone look into this? While I'm at it, is there any reason why only the most significant bit of the return value of VFCmp is defined (according to the documentation)? Both AltiVec and SSE set the components of the result to either all 1's or all 0's. Having only the most significant bit doesn't seem useful to me at all, and (arithmetic) shifting vectors to replicate the bit isn't supported. Thanks!

I have a time series data with 1's and 0's. When the last 3 observations are 1 I want to generate a 1 until I have three 0's in a row and then I want it to produce all zeros again. For example if I have 0101010101 for the first part of the time series this would produce all zeros. Then if the data has 111 my functi...

Hi Nate! I don't see how that would work. Select doesn't work per element. Say we're trying to vectorize the following C++ code: if(v[0] < 0) v[0] += 1.0f; if(v[1] < 0) v[1] += 1.0f; if(v[2] < 0) v[2] += 1.0f; if(v[3] < 0) v[3] += 1.0f; With SSE assembly this would be as simple as: movaps xmm1, xmm0 // v in xmm0 cmpltps xmm1, zero // zero = {0.0f, 0.0f, 0.0f, 0.0f} andps xmm1, one // one = {1.0f, 1.0f, 1.0f...

Hi, I'd like some advice on bootstrapping in R. I have a species x with 20 individuals and a factor containing 0 and 1's (in this case 5 zeros and 15 ones). I want to compare the frequency of the occurrence of 1 with a probability value. This code seems to work to do this in R. attach(test) p <- c(0.5272, (1-0.5272)) sp1_1 <- length(subset(x, x==1)) sp1_0 <- length(subset(x, x==0)) obs1_1 <- c(sp1_...

Hi, Can someone suggest an efficient way to substitute a vector/matrix which contains 1's and 0's to P's and A's (resp.)? Thanks, Lana

Is there a way to map NT names to UNIX names when they are not the same. 95% of our are which is great but we have a few that are different. For example, we have NT user "bigboy" who's Unix account is "smallboy", how can I make an association, oh learned 1's.

Hello, I am almost a total novice, and I am sure there must be an easy (and basic) way to turn a variable of 1's and 2's into a variable of zeros and ones. This is in a data frame, but if I could do it with vectors, that's all I need. Can someone tell me how? Thanks so much, Jen

Hello, I have simulated 30 observations from a binomial(5,0.1) distribution. Now I need to make frequency table( that means I need to tally how many 0's , 1's 2's....... 5's) I know that the simple R function table() will do this, but I am afraid that some times I may get zero frequency for some particular values (for example in the above t...

Hi, I am looking for a way in which I can check if rows in 1 dataframe are present in another data frame in a unique way. A row in dataframe should be super set of any row in another dataframe. I can write a for loop for it, however, that will be inefficient. So, I am looking for an efficient way to do this in R. I have explained it with an example below:...
