similar to: correction to the previously asked question (about merging factors)

First of all, I do not understand why conversion to characters are not allowed. That's what Sundar's solution is doing implicitly (but more elegantly). Here's a test of all three. See the function definitions below. > f1 <- factor(sample(letters[1:3], 1e4, replace=TRUE)) > f2 <- factor(sample(letters[3:5], 1e4, replace=TRUE)) > f3 <- factor(sample(letters[5:7],

Dear R helpers, Suppose I have following data.frame. df <- data.frame(category = c("treat_A", "treat_A", "treat_A", "treat_A", "treat_A", "treat_A", "treat_A", "treat_A", "treat_B", "treat_B", "treat_B", "treat_B", "treat_B", "treat_B",

Dear friends, How do I stop partial matching of list names? e.g., x <- list(AAAA="aaaaa", BBBBB="bbbbb") is.null(x$A) #returns FALSE even though there is no element A. if(is.null(x$A)) {result <- x$BBBB} else {result <- x$A} result #is aaaa even though there is no x$A element x <- list(CCCC="aaaaa", BBBBB="bbbbb") if(is.null(x$A))

Hi everybody. The question: I get two vectors 'iFalseFalse' and 'i2'. I think they should be the same but they are not. Is it because R does not handle complicated logical expressions in such cases or I do something wrong? > z1 = c(NA, "", 3, NA, "", 3) > z2 = c("", "", 3, NA, 3, NA) > cV = (as.character(z1)==as.character(z2))

For example, strings <- c("aaaa", "bbbb","ccba"). How to get "aaaa", "bbbb" that do not contain "ba" ? _________________________________________________________________ [[alternative HTML version deleted]]

Today is a good day for asking question, I guess. > c() NULL > > length(c())==0 [1] TRUE > > r = ifelse(length(c())!=0, c(), c(1,2)) ### OK > r = c() ### OK > r = ifelse(length(c())==0, c(), c(1,2)) ### why this is not OK (given > the previous two)? Error in "[<-"(`*tmp*`, test, value = rep(yes, length =

I think there?s a bug concerning the formatting of raw vectors with names: > structure(as.raw(1:3), .Names = c("a", "bbbb", "c")) a bbbb c 01 02 03 > structure(1:3, .Names = c("a", "bbbb", "c")) a bbbb c 1 2 3 The problem is that EncodeRaw does not honor the requested width, in fact it doesn?t even get the

Hi, everybody. This was an interesting discussion last time and it helped me a lot. Could you please have a look at some feature and tell me why it was designed this way (my questions are under #########) > x = c(1, 10) > y = c(99, 55) > d <- data.frame(x = x, y = y) > d x y 1 1 99 2 10 55 > add <- data.frame(x = 14, y = 99) > add x y 1 14 99 > d <-

The funciton c() works differently for strings and for factors: For strings: > l = c('a', 'b') > l [1] "a" "b" For factors: > l = c(factor('a'), factor('b')) > l [1] 1 1 What should be the right technique for merging factors? -- Svetlana Eden Biostatistician II School of Medicine

Thank you for your answers, I have another question: the behaviour of setdiff(indicesFalse, indicesNA) does not seem predictable to me. > indices [1] 1 2 3 4 5 6 > compareVector [1] NA TRUE TRUE TRUE FALSE NA > indicesNA = indices[is.na(compareVector)] > indicesNA [1] 1 6 > indicesFalse = indices[compareVector == FALSE] > indicesFalse [1] NA 5 NA >

Hi R users, I am new to R and am trying to merge data frames in the following way. Suppose I have n data frames each with two fields. Field 1 is common among data frames but may have different entries. Field 2 is different. Data frame 1: Src Target1 1 aaa 1 bbb 1 ccc 2 aaa 3 ddd Data frame 2: Src Target2 2 aaaa 3 dddd 4 bbbb 4

Hello, I'm having some trouble working on a webapp managing the imap tree on Dovecot. The same doesn't happen on other imap servers (e.g. Cyrus). Looks like if I receive shared folders from another user, and try to rename a folder in it, the rename command returns "ok", then if you list the new folder name, it isn't there. Looks like you've lost all the original folder

I've been trying out IPv6 networking with tinc and noticed that it will not route smaller segments than /48 If I try to run ip -6 route add aaaa:bbbb:cccc:dddd::/64 dev tun0 I get network unreachable However if I run ip -6 route add aaaa:bbbb:cccc::/48 dev tun0 it works fine Is this is a limitation in tinc or the kernel network stack itself? -------------- next part -------------- An HTML

I've the following error : Doing a node status request to the domain master browser at IP aaaa.bbbb.cccc.dddd failed First time I configure my smb.conf file on a server with the adress aaaa.bbbb.cccc.dddd For some raison I have to change this address for another.

Thanks for the previous tips and suggestions. Here's a more concise example: Input file: <aaaa> <bbbb> <cccc> <dddd> I want everything on one line, i.e., remove all newlines. Like so: <aaaa><bbbb><cccc><dddd> Simple perl code: #!/usr/bin/env perl # Remove newlines from a file in two ways: # (1) Just "chomp" them; # (2) Replace
