Re: [R] sub-setting rows based on dates in R

Hi Md, This kind of clunky, but it might do what you want. df1<-read.table(text="DateRainfall_Duration 6/14/2016 10 6/15/2016 20 6/17/2016 10 8/16/2016 30 8/19/2016 40", header=TRUE,stringsAsFactors=FALSE) df1$Date<-as.Date(df1$Date,"%m/%d/%Y")

Re: [R] HELP with GLM

Dear Xavier: It sounds like you have a right mess! Perhaps others cleverer and more diligent than I can sort through it and diagnose the problem. However, it really *does* sound like you need to step back, take a deep breath, and spend some time with an R tutorial or two (there are many good ones

Re: [R] Failure to understand namespaces in XML::getNodeSet

Hadley, It’s sometimes amazing the mistakes I can make. No, it did not do what I wanted, which was read_xml(str_c(with_ns_xml, collapse = “") Reproducible example follows: library(stringr) library(xml2) ## Given the correct argument value for collapse, the next two lines work no_ns <-

Re: [R] caculate correlation

Hi Elham, It looks to me as though you are looking for matches in the name field and then asking for all columns except the first (-1). If you only have two columns in "coding.rpkm", and "name" is the first column, you will get whatever is in the second column that has a match in the "name"

I think you want x <- read_xml(' http://labkey.org/etl/xml;> MFIA 9-Plex (CharlesRiver) ') The collapse argument do what you think it does. Hadley On Tue, Jan 31, 2017 at 5:36 PM, Mark Sharp wrote: > Hadley, > > Thank you. I am able to get the xml_ns_strip() function

Re: [R] Failure to understand namespaces in XML::getNodeSet

Hadley, Thank you. I am able to get the xml_ns_strip() function to work with my file directly so I will likely be able to reach my immediate goal. However, I still have had no success with understanding the namespace problem. I am not able to use read_xml() using the object I generated for the

Hi Kwesi, I worked through your code below, and I think that when you have the two variables "mon.t1" and "seas.t1" you can select a "rolling quarter" like this: # the file name in your example is different from the one you sent era<-read.table(file="SAfr_700hpa_7x5II.txt",header=FALSE,sep=" ",
