Re: [R] Non date value

DF1 is a data frame. I am suspecting there might be non date value in that column. My question is how to remove a non date values from that field. example if Alex152 has 12253,. This value is not a date format. On Fri, Apr 14, 2017 at 11:24 PM, Bert Gunter wrote:

Show us str(DF1) . It is not a data frame. -- Bert On Fri, Apr 14, 2017 at 9:02 PM, Ashta wrote: > Hi all, > I am reading a field data that contains several variables. The sample > of the data with the first two variables is shown below. I wanted to > know the minimum

Re: [R] Can this be done in ggplot?

A very dirty solution. I hope someone can give a better solution: library(ggplot2) set.seed(1) df <- expand.grid(g = factor(1:4), f = factor(c("a", "b", "c"))) df <- df[-1, ] # some factors are not present in certain groups df$v <- runif(nrow(df)) library(dplyr) df <- df %>% arrange(g,

Re: [R] seq argument along.with

Hi Jeff I have seen the seq_along function but never knew the what or why of it.  Your response is much appreciated and just shows how brilliant the creators of R were/are. Thank you for enlightening me. Carl Sutton On Friday, April 14, 2017 3:54 PM, Jeff Newmiller

Re: [R] seq argument along.with

Have you ever used the seq_along() function? If you want to delegate the decision of how many elements you want to process to some earlier point in your (or someone else's) code, then the most logical way to create a result vector that is the same size as some input vector, even if that vector

[R] seq argument along.with

Hi just messing around today and am now perplexed by the seq argument "along.with". Please, I am just just seeking some knowledge here. Obviously I missed a point and would like to know what it is. seq(1,10,length.out = 2) makes sense seq(1,10,by = 2) makes sense seq(1,10,

Re: [R-es] Variograma - Bins

Hola Carlos, Los paquetes gstat y geor fijan el número de saltos sin ningún criterio. La recomendación sería determinar un número de saltos de forma que el número de aportaciones al primer salto sea en torno a 30 (20 podría valer...) y considerando hasta la mitad del máximo salto posible. Un

[R] Can this be done in ggplot?

Hi, I need to bars to display in order based on the values of "v" within each group "g". Is this possible? library(ggplot2) set.seed(1) df <- expand.grid(g = 1:4, f = factor(c("a", "b", "c"))) df <- df[-1, ] # some factors are not present in certain groups df$v <- runif(nrow(df)) ggplot(df,
