How to make lookup() look for a larger value?


How to make lookup() look for a larger value?

wish helps you One way is to let the function return 'class A' but to wrap it in a function that looks as the cell below that:
code :
=offset(vlookup(C1,A:B,2),1,0)  
=index(B:B,match(C1,A:A)+1)

How To Make Sprites Larger

like below fixes the issue .png sprites works because you use pixels to peep onto a restricted area of a larger image. This means you can't zoom them very easily. You can't do anything that effects the co-ordinates that picks out the sprite image without exposing other sprite images, unless you zoom the size of the underlying image correspondingly. You then need to do it by an exact multiple of pixels (so exact 2x or 3x) to avoid bleeding - this might not fit your designs.
With any zooming on a pixel based image quality will be lost.

around this issue You have to set translateZ() of the transform property of each page to a half of your side length, e.g. translateZ(150px) for a side length of 300px. It's the distance of the 6 side planes to the center.
code :
body {
  padding: 0;
  margin: 0;
}
.container {
  perspective: 800;
  width: 100%;
  height: 100vh;
  background: #010101;
}
.cube {
  position: relative;
  top: 160px;
  margin: 0 auto;
  height: 300px;
  width: 300px;
  animation: spin 9s infinite linear;
  transform-style: preserve-3d;
  opacity: .8;
}
@keyframes spin {
  from {
    transform: rotateY(0) rotateX(0);
  }
  to {
    transform: rotateY(-360deg) rotateX(360deg);
  }
}
.cube > div {
  position: absolute;
  width: 300px;
  height: 300px;
}
.one {
  transform: rotateX(90deg) translateZ(150px);
  background-color: #E349BB;
}
.two {
  transform: translateZ(150px);
  background-color: #BB493E;
}
.three {
  transform: rotateY(90deg) translateZ(150px);
  background-color: #f00de7;
}
.four {
  transform: rotateY(180deg) translateZ(150px);
  background-color: #dec011;
}
.five {
  transform: rotateY(-90deg) translateZ(150px);
  background-color: #bac35d;

To fix the issue you can do The following algorithm will work for any size of the lookup texture. You just have to adapt tiles to the number of the tiles in the x and y direction, and colTexSize to the full size of the color lookup texture.
The algorithm is identical to the original algorithm, except the constant size values, which have been replaced by the variables tiles and colTexSize.
code :
void main()
{
    vec2 tiles      = vec2( 4.0, 4.0 );   // original texture vec2( 8.0, 8.0 )
    vec2 colTexSize = vec2( 64.0, 64.0 )  // original texture vec2( 512.0, 512.0 )

    highp vec4 textureColor = texture2D(inputImageTexture, textureCoordinate);

    highp float blueColor = textureColor.b * ((tiles.x*tiles.y)-1.0);

    highp vec2 quad1;
    quad1.y = floor(floor(blueColor) / tiles.y);
    quad1.x = floor(blueColor) - (quad1.y * tiles.x);

    highp vec2 quad2;
    quad2.y = floor(ceil(blueColor) / tiles.y);
    quad2.x = ceil(blueColor) - (quad2.y * tiles.x);

    highp vec2 texPos1;
    texPos1.x = (quad1.x / tiles.x) + 0.5/colTexSize.x + (1.0/(tiles.x - colTexSize.x) * textureColor.r);
    texPos1.y = (quad1.y / tiles.y) + 0.5/colTexSize.y + (1.0/(tiles.y - colTexSize.y) * textureColor.g);

    highp vec2 texPos2;
    texPos2.x = (quad2.x / tiles.x) + 0.5/colTexSize.x + (1.0/(tiles.x - colTexSize.x) * textureColor.r);
    texPos2.y = (quad2.y / tiles.y) + 0.5/colTexSize.y + (1.0/(tiles.y - colTexSize.y) * textureColor.g);

    lowp vec4 newColor1 = texture2D(inputImageTexture2, texPos1);
    lowp vec4 newColor2 = texture2D(inputImageTexture2, texPos2);

    lowp vec4 newColor = mix(newColor1, newColor2, fract(blueColor));
    gl_FragColor = mix(textureColor, vec4(newColor.rgb, textureColor.w), intensity);
}

seems to work fine I am not good at data.table but here's a tidyverse way that might help you -
code :
dt_1 %>% 
  tibble::rownames_to_column("id") %>% 
  mutate(cj = 1) %>% 
  inner_join(dt_2 %>% mutate(cj = 1), by = "cj") %>%
  select(-cj) %>% 
  mutate(
    closeness = abs(Observed_A - Modeled_A) + abs(Observed_B - Modeled_B),
    # closeness = 0 means perfect match
  ) %>% 
  arrange(id, closeness) %>% 
  group_by(id) %>% 
  slice(1) %>% 
  ungroup()

# A tibble: 8 x 9
  id    Observed_A Observed_B Modeled_A Modeled_B Variable_1 Variable_2 Variable_3 closeness
  <chr>      <dbl>      <dbl>     <dbl>     <dbl>      <int>      <int>      <int>     <dbl>

this will help First, remove source of crashes: startPreviewCamera called in onResume. Camera preview shall be started in SurfaceHolder.Callback methods.
Then you should know that you can set preview size only to sizes reported by Camera.Parameters.getSupportedPreviewSizes. And these sizes will most likely be smaller or equal to device's screen size.
