R:How to attach parts of a data frame with different headers and/or an overflowing piece of the dat frame

wish of those help We split the dataset in to a list of 'data.frame's based on the occurence of uppercase letters in 'X', loop through the list ('map'), change the column names with those having first row as letters, then we make a single dataset with bind_rows, grouped by 'Keg', get the sum of the other columns
library(tidyverse)
nm1 <- c("A", "C", "D", "E", "F", "G")
split(df1, cumsum(grepl("[A-Z]", df1$X))) %>%
       map(~ if(any(grepl("[A-Z]", .$X))) { 
               names(.) <- unlist(.[1,])
              .[-1,]
       } else .) %>% 
            map(~ .[names(.) != ""]) %>% 
            bind_rows %>%
            group_by(Keg) %>%
            summarise_at(vars(nm1), funs(sum(as.numeric(.), na.rm = TRUE)))

# A tibble: 7 x 7
#    Keg     A     C     D     E     F     G
#  <chr> <dbl> <dbl> <dbl> <dbl> <dbl> <dbl>

How to attach a simple data.frame to a SpatialPolygonDataFrame in R?


Tag : r , By : Santhanam

this one helps. Let df = data frame, sp = spatial polygon object and by = name or column number of common column. You can then merge the data frame into the sp object using the following line of code
sp@data = data.frame(sp@data, df[match(sp@data[,by], df[,by]),])

This might help you The basic problem is that you are overriding the wrong method in the JPanel. You have:
 @Override
public void paintComponents(Graphics g) {
 @Override
public void paintComponent(Graphics g) {

will help you Though I'm not sure why you would want to do this, you could have both as elements of a list. As an example:
report <- list()
report[[1]] <- "Report Name"
report[[2]] <- head(mtcars)
report
[[1]]
[1] "Report Name"

[[2]]

Get row indices of data frame A according to multiple matching criteria in that data frame and another data frame, B

I hope this helps you . Let's say we have two data frames in R, df.A and df.B, defined thus: , 1) Using SQL it can readily be done in one statement:
library(sqldf)

sqldf('select a.rowid
       from "df.B" b 
       left join "df.A" a on obs_min >= bin_min and obs_max <= bin_max')

   rowid
1      4
2     NA
3      5
4      2
5     NA
6      4
7      3
8      4
9      5
10     2
m <- merge(df.B, df.A)
stack(by(m, as.numeric(sub(".*_", "", m$obs_ID)), 
      with, c(which(obs_min >= bin_min & obs_max <= bin_max), NA)[1]))
   values ind
1       4   1
2      NA   2
3       5   3

6       4   6
7       3   7
8       4   8
9       5   9
10      2  10
sapply(1:nrow(df.B), function(i)
  c(which(df.A$bin_max >= df.B$obs_max[i] & df.A$bin_min <= df.B$obs_min[i]), NA)[1]) 
[1]  4 NA  5  2 NA  4  3  4  5  2
mapply(function(x, y) c(which(x >= df.A$bin_min & y <= df.A$bin_max), NA)[1], 
       df.B$obs_min, 
       df.B$obs_max)
seq_len(nrow(df.A)) %*% 
  (outer(df.A$bin_max, df.B$obs_max, ">=") & outer(df.A$bin_min, df.B$obs_min, "<="))

hop of those help? Okie. Figured this out. All I had to do was to change the grep to ignore case.
nm1 <- c("EA_A", "EA_B", "EA_C", "EA_D", "EA_E", "EA_F", "EA_G","EA_H")
temp = split(df1, cumsum(grepl("[A-Z]", df1$tar, ignore.case = TRUE))) %>%
  map(~ if(any(grepl("[A-Z]", .$tar, ignore.case = TRUE))) { 
    names(.) <- unlist(.[1,])
    .[-1,]
  } else .) %>% 
  map(~ .[names(.) != ""]) %>% 
  bind_rows %>%
  group_by(Keg) %>%
  summarise_at(vars(intersect(nm1, names(.))), funs(sum(as.numeric(.),
  na.rm = TRUE)))
