Re: [R] Stacking two graphs with different x and y scale on the same graph

Dear Rui, Many thanks. It is indeed close to what I am looking for apart from the issues on the axes. I am attaching the result plot. The minimum and maximum values of y1 are respectively -5.470919 and 1.298329 while they are 0.0002937659 and 4.808186 for y2. New problems are: (1) I can't labelle

Re: [R] Stacking two graphs with different x and y scale on the same graph

Hello, The following is not a complete solution, the axis ranges are wrong, but it gets you closer, I think. op <- par(mar = c(5, 5, 5, 5)) plot(c(x1, x2), c(y1, y2), type = "n",xaxt="n", yaxt="n", ylim = range(c(y1, y2))) par(new=TRUE) plot(x1,y1,pch=0,type="b",col="red",yaxt="n",

Re: [R] Conditions

Hi Val, Here's an answer using a series of ifelse() statements. Because the d4 column is created initially using NA as a placeholder, you can check your conditional logic at the end using table(!is.na(dat2$d4)): > dat2 <-read.table(text="ID d1 d2 d3 + A 0 25 35 + B 12 22 0 + C 0 0 31 + E 10 2

Re: [R] Conditions

Hi val, You had a "conditional leak" in your ifelse statements: dat2 <-read.table(text="ID d1 d2 d3 A 0 25 35 B 12 22 0 C 0 0 31 E 10 20 30 F 0 0 0", header=TRUE,stringsAsFactors=FALSE) dat2$d4<- ifelse(dat2$d1,dat2$d1,ifelse(dat2$d2,dat2$d2,ifelse(dat2$d3,dat2$d3,0))) Even though it works, it i

Re: [R] Conditions

I generally find nested ifelse's to be confusing and prone to error, so I usually prefer to proceed sequentially using subsetting with logicals or replicated, but not nested ifelse's. In your example, the translation to logical indexing seems pretty straightforward. Using your example: > dat2 <-w

[R] Conditions

HI All, I am having a little issue in my ifelse statement, The data frame looks like as follow. dat2 <-read.table(text="ID d1 d2 d3 A 0 25 35 B 12 22 0 C 0 0 31 E 10 20 30 F 0 0 0",header=TRUE,stringsAsFactors=F) I want to create d4 and set the value based on the following conditions. If d1

Re: [R] giving priority to stats package

I was thinking of using length(search())+1 to be safe and simple. Using grep gives higher priority than length while still solving your issue. On Mon, Nov 25, 2019 at 3:06 PM Gabor Grothendieck wrote: > > Goold idea. This seems to work. > > library(dplyr, pos = grep("package:stats", search())

[R] Hyperparameter tuning

I am using xgboost hyperparameter tuning for the value of rmse. I used the following method which returns two values ; mean which is like - 1200.12 and Best value like - 960. I guess the first value is average value and the second is the best rmse value returned by the algorithm. Now if we have to

This may or may not fix your problem but I avoid installing R packages in system libraries... using user libraries without running R as root or with sudo makes life much simpler unless you are a professional sysadmin. On November 26, 2019 7:06:48 AM PST, Manish Gupta wrote: >I am getting follo
