[R] Sharing an R installation via NFS on ubuntu cluster

hi all, i want to share an R installation from a master node to several compute nodes via NFS. all nodes run ubuntu 16.04. I tried building R from source but hit a wall several times because of missing dependencies. So I am looking for something that uses the usual apt-get install proceedure, but

Re: [R] Ggplot error

I get the same result as Eric  withR version 3.4.2 (2017-09-28) Platform: x86_64-pc-linux-gnu (64-bit) Running under: Ubuntu 17.04 It looks like you have "tidyverse" loaded so I tried it with just ggplot2 loaded and with tidyverse loaded.  On Wednesday, November 8, 2017, 4:16:14 AM EST,

[R] dendrogram adjustment in heatmap.2

Dear R Community, Is there a way to adjust the line width of the dendrogram in heat map.2 function? I tried "lwd", but it didn't work... Also, is there a way to adjust the general height/width/position of the dendrogram using heatmap.2 function? I feel the portion of the dendrogram is huge

Re: [R] Adding Records to a Table in R

Hi Paul, The following worked for me: library(lubridate) dataset1 <- read.csv("dataset1.csv",stringsAsFactors=FALSE) dataset1$TransitDate <- mdy(dataset1$TransitDate) TransitDateFrame <- data.frame(TransitDate=seq(as.Date("1985-10-01"), as.Date("2017-10-01"), by = "month")) dataset1NEW <-

Re: [R] Adding Records to a Table in R

Hi Instead of attachments copy directly result of dput(TransitDateFrame) and dput(dataset1) to your email. Or, if your data have more than about 20 rows you could copy only part of it. dput(TransitDateFrame[,1:20]) dput(dataset1[,1:20]) Only with this approach we can evaluate your data in all

Re: [R] Adding Records to a Table in R

Dear Eric, Hope you are doing great. I also tried the following: #First I created the complete date sequence TransitDateFrame <- data.frame(TransitDate=seq(as.Date(dataset1[1,1]), as.Date(dataset1[nrow(dataset1),1]), by = "month")) #Then I did the merging dataset1NEW <-

Re: [R] Adding Records to a Table in R

Dear Eric, thank you for your kind reply, Assume dataset1Frame is the table containing the missing dates, and TransitDateFrame <- seq(as.Date(dataset1Frame[1,1]), as.Date(dataset1Frame[nrow(dataset1Frame),1]), "months") #dataset1Frame is basically reading some fields from a SQL Server table,

Thanks, I think, I found the problem. It seems to related locale setting. If I start with 'LANG=C R' everything's good. -- Zeki Çatav zekicatav.com On Nov 8, 2017 1:56 PM, "John Kane" wrote: I get the same result as Eric with R version 3.4.2 (2017-09-28) Platform:
