Dear helpeRs- I'm using a for loop to create a series of models. I'm trying to assign a name to each model created, using the loop index. The loop gets stuck at the name of the model, giving the error "target of assignment expands to non-language object". The linear model runs without error; only the name is problematic. Here is the current loop syntax. The use of dat

Hi! I'm trying systemtap on CentOS 6.2 kernel-2.6.32-220.23.1.el6.x86_64. My problem is that I can't find kernel-debuginfo... corresponding to my kernel version. The systemtap docs suggest rebuilding the kernel from sources, but it looks like I will have to install my own kernel, which is not acceptable on the production machine. Where can I find the debuginfo for the latest CentOS

Iam using R version 2.15 in a linux operating system. I have a matrix consisting of the gene ids and their specific signal intensity values as follows( a subset of the whole matrix) : probes GSM362180 GSM362181 GSM362188 GSM362189 GSM362192 244901 5.094871713 4.626623079 4.554272515 4.748604391 4.759221647 244902 5.194528083 4.985930299 4.817426064 5.151654407 4.838741605

Dear Helpers, I wonder whether you might be able to help me. I have a plot composed of ggplot (and a follow on geom_smooth call). I would like to restrict the display range of the y axis to a smaller range, a sort of zooming onto a region. I attempted to use ylim, but it will effect the range (i.e. effect the geom_smooth call). Is there any way that I can save the results up to geom_smooth call

Dear R Helpers, I need to read time from a .csv file which is formated as chartime (09:12:00) below. I need to add one minute (cf chartime2). Then I need to output the value just as 09:13 without the seconds for writing a csv file and input in another program. I get it with the following reproducible example but I can't help thinking that there must a less clumsy way to do that ! Thanks

I have a numerical vector which contains a (poorly) formatted time column, which, in theory, should be HHMM, but was distributed as an integer, so, for 12:15 am, it is saved as "15" (e.g. HHMM = 0015 with the zeroes stripped). I'm trying to use this in conjunction with strptime, but I'm thinking because each time is an integer ranging from 1 to 4 digits, I probably need to

I'm a bit of an amateur R programmer. I can do simple R scenarios but my handle on complex grammatical issues isn't steady. I have 12 CSV files that I've read into dataframes. Each has 8 columns and over 2000000 rows. Each dataframe has data associated by time component and a date component in the format of: X.DATE and then X.TIME X.DATE is in the format of MMDDYYYY and X.TIME is

Hello, I want to build an application where i have client and server. I need to exacute commands with XM-RPC. I can get all this working, following the howto''s in wiki and main website. But the problem is they are all unsecure. I can''t seem to find any web service examples where they use authentication, or ssl. Just wondering if anyone know how i go about doing this. At the

Dear R users, Given this data: x <- seq(1,100,1) dx <- as.POSIXct(x*900, origin="2007-06-01 00:00:00") dfx <- data.frame(dx) Now to play around for example: subset(dfx, dx > as.POSIXct("2007-06-01 16:00:00")) Ok. Now for some reason I want to extract the datapoints between hours 10:00:00 and 14:00:00, so I thought well: subset(dfx, dx >

Running 9.0-Stable on an i386. Whenever I type a command at the prompt I get the output /usr/local/lib/libintl.so.9: Undefined symbol "_ThreadRuneLocale" and nothing else - the command will not run. Just the above output. Commands like "ls" and "exit" work, but not much else. This happends whether I am logged in a user or as root. Cannot even halt the system from

When I do the date +%Z I get the timezone. Which currently is EDT. I am sending information to another system, that says EDT is not a valid timezone. I have no way to modify the other system. My question is - is there a way to get the non-day-lite savings time zone ? For example EST is valid - EDT is not. Just curious if there is an easy way already present to get a standard time zone. Thanks,

Hi, I was installing hundreds of packages on a machine with a single call to install.packages() and after a long time the call to install.packages() finally returned with the following warnings and errors: Warning messages: 1: packages ?hgu133aprobe?, ?hgu95av2.db?, ?BSgenome.Celegans.UCSC.ce2?, ?BSgenome.Mmusculus.UCSC.mm10?, ?BSgenome.Dmelanogaster.UCSC.dm3.masked?,

?Hola, Es más fácil que todo eso... Es que en tu fichero de entrada, la segunda fila son las unidades de las variables que tienes en la primera fila, pero "R" al leerlas las considera como un string que altera la clase de toda la columna cuando ésta es numérica. Simplemente eliminando esa segunda fila, las columnas acaban teniendo la clase que deben..

Dear helpeRs, I am attempting to read in a series of csv files so I can bind them into one large dataframe. I have written the following script: test <- list.files(".", pattern = "csv") #lline 1 imp <- list() #line 2 for (i in 1:length(test)) { #line 3 imp[i] <- read.csv(test[i]) #line 4 }

Previously I had problems with data(foo) and Gass and I had problems with help(). His diagnostic was "POSIX regular expressions not available" and mine was "invalid regular expression". Martin Maechler has no problems with Solaris 2.5 and suggested a regular expression library was needed, e.g., regex-x.xx. Solaris 2.4 has regex.o in /usr/ccs/libgen.a and regex.h in

Dear helpeRs, I have a dataframe (14947 x 27) containing measurements collected every 5 seconds at several different sampling locations. If one measurement at a given location is less than zero on a given day, I would like to delete all measurements from that location on that day. Here is a toy example: toy <- data.frame(CH = rep(3:5,3), DAY = c(rep(4,5), rep(5,4)), SLOPE =

Hi, I'm newish to R, a recent convert from Matlab... So far I'm impressed, and determined to solve the following problem, which seems like it should be easy: I have a long (millions of points) data series recorded with a datalogger that produced a timestamp in 4 columns: Year, Day of Year, Time in (H)HMM and Seconds. I would like to have R interpret these columns as a time object and have
